|0005991||Dwarf Fortress||Dwarf Mode -- Jobs, Building Construction and Destruction||public||2012-06-06 08:48||2014-08-11 18:11|
|Assigned To||Toady One|
|Priority||normal||Severity||minor||Reproducibility||have not tried|
|Target Version||Fixed in Version||0.40.05|
|Summary||0005991: Dwarf tries to build wall standing on the construction site|
|Description||Trying to build towers, I get a couple of repeatable situations where dwarves ordered to build a wall stand on the wall square and then "cancel job: creature occupying site"|
|Additional Information||This is the arrangement that caused me trouble. Its rotation by 180 degrees also caused the same issie but mirror images and rotations of 90 degrees worked fine. There is access to the floors south of the construction site. I tried constructing and deconstructing the walls next to the construction site which made no difference. I did eventually get the walls built by in one case deconstructing the ramp and in the other case by building a floor grate above it. Once I did that the dwarves constructed while standing in the square diagonally opposite the ramp|
up-Ramp - wall - clear
wall - wall - wall
clear - clear - clear
down-ramp - wall/clear - clear
wall/clear - build-site- wall/clear
floor - floor - floor
wall = constructed wall, clear = no wall: walking on ground or on top of the walls below, floor = constructed floor
Reminder sent to: Lazygun
Although your diagram looks clear, it might still help to upload a save to http://dffd.wimbli.com/ [^] and post the link here.
I've one that at http://dffd.wimbli.com/file.php?id=6436 [^]
It looks like this is a sometimes repeatable problem
|Did you use an old save? Somebody I know did, and he's got the exact same issue.|
|That's a good point. I started this fort in 0.34.10|

I have run into this issue in my current fort, which was started from scratch on 34.11. To fix, I had to cancel the wall being built and build it again in the exact same place. The dwarf would cancel the build because of creature occupying site. I had already fixed the issue, but if it happens again, I will upload a save. Diagram below:
# = Wall built already
+ = Accessible soil floor
D = Down stairs (to accessible fort)
X = Walls that would not complete
Edited to pretty my diagram.

I've experienced the same problem with this brand new fort, trying to build a wall in a dug out staircase. This is a new world built in 34.11. Check the bottom of the stairs right next to the embark point. I immediately hit a cavern so I tried to build a wall. It doesn't matter if I delete it and try again; the builder just stands on top of the site, then cancels.
This build and save uses the LazyDorf repack uploaded June 5th, and the Mayday graphics set.
Update: I noticed a stone was sitting on the construction site so I dumped it. After than the dwarves were able to properly complete the wall.
|I just got the same thing. Tried destructing all the buildings around it and it still wouldn't work.|
I'm attempting to build some walls in a murky pool (after draining) so wagons can get to my depot. http://koboldi.net/dwarffortress/mason-fail.png [^] is a screenshot of the two tiles I am experiencing this on.
The woodworker is removing an existing wall, as I'm hoping that will allow me to build the bottom right one (on the ramp). Deconstructing the wall directly south of the woodworker allowed me to build the wall SW of the woodworker, when the mason would stand in the square otherwise.
This is a new 34.11 world (Phoebus 34.11v00 for linux).
I have a save with a similar situation.
I'm trying to build a 2 story tall room on the surface, and built a bridge for cheap access to the upper wall tiles.
The mason walks along the bridge, then moves diagonally from the bridge to the wall construction. Then cancels because he is in his own way.
My thought was that he was doing it because during his trip to the construction site, he never actually stepped on a legal tile to build from.
Building a second bridge and applying traffic designations proved that false; he walked through the legitimate tile, and then tried to build on top of himself again.
Cancelling the construction and redesignating it worked however.

Same thing here, in a new 34.11 world. The two ends of a 9-tile rock block wall could not be built. Cancelling the almost completed construction and redesignating corrected the condition. I guess I don't need to upload a save. Plenty of saves available above.

Got a better save than above:
edit: zip was corrupted. recreated & uploaded again.
In this case, I'm trying to extend the wall between the trap entrance and the wagon entrance on the south wall of the fort. (1 z-level above the surface)
The mason's preferred path to the construction site involves going up a ramp which places him directly on the tile to be walled.
He tries to build while on the tile, rather than walking an extra space (to somewhere he's never actually been) and building successfully.
+ = floor
v = ramp on z-level below
O = Previously built walls
X = construction site
I tried a some tests:
1) Cancelling and redesignating did not fix it - dwarves preferred to approach from the ramp, and never set foot on the floor access.
2) Designating the bridge and ramp as restricted did not fix it. Dwarves would approach from the floor access and then try to use the original mason's illegal build location.
3) Restricting the ramp AND cancel/redesignate does work. This time the first builder approaches from the floor and builds successfully.
4) Once the first mason has decided to build from the floor side, the task can be suspended and the restrictions lifted. The replacement mason will approach from the ramp, but then walk to the floor tile the first mason was working from.

Same for me in 34.11
Happend on following Construction:
W = Natural Wall
^ = N. Ramp
+ = N. Floor
C = Constructed Wall
c = Ordered Wall with a ramp on this tile
(which gives the bug mentioned in this thread)
Removing ramp and reordering (delete and new construction) solved the problem
|Same here with a fresh world generated in 34.11 on the Mac. Makes the current version unplayable for my needs. No amount of canceling/un-suspending works. I can force the issue by channeling out the area I want a wall in, but that makes for other problems.|
Same problem. Standard 34.11, first and only fortress so far. Downloaded and installed recently on Windows.
Simple tower. Several free tiles for the mason to stand on, but he repeatedly chooses to stand on the tile he is constructing a wall on (even if cancelled and replaced with a new build order). This causes:
<Name> cancels Construct Building: Creature occupying site.
Like Castellan, I feel that this makes the current version pretty much unplayble, since construction is critically important. Trying to work around the bug is just an exercize in pain and frustration.
This bug appears to also apply to deconstructing floors.
Dwarfs will try to deconstruct from the same tile and fall into the dangers below.
I experienced the "stand on wall" bug in my first 34.11 game. Cancel-And-Redesignate did not help in that case.
I was able to get this save: http://dffd.wimbli.com/file.php?id=6592 [^]
It shows a similar issue. Even though Urist and the-blocks are on the "left" side of map, the Urist paths to the "top-right" corner to build several walls. For some walls, Urist even walks over empty grass, and goes farther just to build the wall.
Hope this helps
This bug made my current game very hard... I channeled out a long straight cliff and was going to build a wall on the edge of it:
Look from the side (.air ^ramp f-natural ground C-wall construction order)
I ordered construction of walls along the edge
And at the same time designated removal of the ramps
Then I've got this (top-down view):
where W - successfully built wall, s - suspended construction due to "creature occupying site"... Either resuming or cancelling-rebuilding does not help, worker stands on the same tile he builds the wall on... Dwarf behavior looks completely random to me (I know they are insane, but anyway)...
|Same here. Unsuspending the construction never helps. Cancelling and rebuilding sometimes help.|
I have actually been having pretty good luck with canceling the job, waiting for the surrounding constructions to be completed, removing any ramps in the tile, and redesignating the wall. It still fails every now and then, but this almost always works.
I wonder if this is emergent behavior from the worker not wanting to stand in a tile designated for another construction, combined with the new construction code that allows them to build diagonally?
I have the same problem, I was trying to do the bucket method of making a farm (Carve out a room below, and have it designated as a pond zone) but I didnt take something into consideration and wound up with a room too big for the buckets to fill.
When I tried to fill up the excess gap using walls, I had dwarves end up standing on the spot where they tried to build, causing the "Creature Occupying Site" error. Luckily I solved it by canceling the wall and rebuilding it.
|So far what I've noticed, is that this happens mostly when there's a down ramp in the surrounding eight tiles - It's what I've noticed on my maps and after I deconstruct/remove the ramp, the building continues along just fine. I'll do a little testing to see if there's anything else that causes the problem.|
|My case was also with a down ramp.|
|I think this bug is related to down ramps - most if not all cases here seem to be building them with one nearby. I'll see if it's because they decide to go up the ramp to start the job or if it's just the placement of the ramp in the area that makes it happen. I'm almost positive it's the first case.|

Yeah, I've got a workaround figured out. Designate the up/down ramp as a restricted area and make a high traffic road as a detour around the down ramp, so he builds from a different direction.
It's caused by the dwarf going up the down ramp to build the wall, but since he can't occupy the space where the ramp is, he ends up where the wall is to be constructed, so far as I see.
|The instances where I have had this issue occur had no up/down ramps anywhere near the construction area.|
|Hmm. See if they come in on a diagonal. I've seen a few dwarves building that way so that may be the issue as well, because from what I got from the wiki, they have to be directly adjacent to the wall. That doesn't seem to be the case anymore as I've seen them build like that.|

Not neccisarily down ramp related. I had the same problem; clear space, dorf works building wall -- silly statement
unsuspend -- dorf ignores
tried a second place also not near a ramp.
It was annoying because it let a blind ogre ruin my whole camp.
btw in 34.11
|I've had the same problem, but I've also had a minor case crop up when just building a normal, straight wall on normal, flat ground. The dwarf will stand on the tile she's trying to build on until I remove the wall construction site and build it again. :(|
I saw this over the weekend with a 2 wide hall, building a wall...
W = natural wall
w = Proposed construction
+ = floor
A = Carved fortification
that last square, they just can't build it!
Some tests after reading this log:
Had a wall that stubbornly refused to be built a la this bug.
It was adjascent to a ramp, like so: +=const. floor, v=DRamp, .=grass, O=wall, *=wall in question, =open space
This never ever worked. So I built around it to this:
Canceled and retried. It worked.
Seems to be about arriving on a diagonal, yeah.
|PS: copy to Notepad or something Monospace to see my diagrams right >.<|

I can confirm this bug I have managed to work around but I'm not exactly sure how to do it.
Sometimes its as simple as cancelling the construction and starting it again
sometimes i have to deconstruct it and move it.
Looks like a bug in the part of the code that stops the dwarf from walling themselves in. Because It has never happened until that feature was added.
|It looks like channeling the square where the wall will be built works (obviously since the dwarves are forced to stand somewhere else). It's harder when building above ground level, because then you might have to remove a construction.|
Changing the construction order works as well, probably because this gives the dwarf a different option on where to stand.
Now that I think about it, when I cancel the construction and the building materials appear, they almost always appear in the NW tile (upper left) of those adjacent to the construction site. I'm thinking this is a useful bit of information in troubleshooting the problem.
|This problem happens if the dwarf doing the job, while in the phase of bringing the build item to the tile, reaches the tile via a path that doesn't cross any of the tiles that can be used to actually build the construction. As a result, the tile to work from is not set and remains equal to the position of the construction.|
If you are right, ag, then the diagonal positions that dwarves build from are not always considered "valid" sites to build from.
On top of a 1 tile wide east-west wall I build flooring off the south side for a walkway, then designated more wall tiles on top:
The X above is the wall tile that the masons continually stood on instead of next to when building. The wall was constructed from right to left, and every other tile worked just fine, with the dwarf standing SW of the wall tile constructed.
|I actually recently found the code that may be responsible by chance. What it seems to be doing is that when the worker first appears in the 3x3 square surrounding the construction, it changes the job location to the current position of the worker, and sets a flag in the job. If the unit somehow manages to appear directly in the center location via a ramp or otherwise, it still fires and permanently locks the wrong location. Clearing the flag using lua fixes it, because the next worker to do the job can rerun the code.|
|It is sad to see that this bug is still present in 0.40... It's so annoying...|

Hopefully Toady will get to it soon.
It is one of the two annoying bugs that were introduced in 0.34.11, the last bugfix release before the two years of 40.01 development, so unfortunately they had to stay all that time.
The other one being 0005994.
