0005994: Destroying a construction teleports nearby items
Destroying a wall empties the wood stockpile.

For example, I'm trying to destroy this wall:
http://i.imgur.com/w3clU.png [^]

Notice that It uses only 4 wood. When is destroyed, some wood from my wood stockpil is autoteleported to the destroyed zone. Now there are 10 woods in the destroyed area instead of only four.

Place a wood stock pile.
Build a wooden wall.
Destroy the wall.
I don't know if this happens only outside.

Do you have any utilities like DFHack plugins enabled that could cause this?

Also please upload a save which demonstrates this bug to DFFD:
http://dffd.wimbli.com/ [^]

2012-06-07 04:30   
I don't use any plugin or tool, but DwarfTherapist.
I have not dumping zone, by the way.

How could I demonstrates this bug? It needs a "before" and an "after". How could I save two times?

(edited on: 2012-06-07 04:39)
Probably the same issue, so not making a separate post.

Pretty much the same, except for me it happens at least with walls and floor (so maybe all constructions?), and teleports the contents of my nearby 1-square garbage dump there when deconstruction finishes. A lot more than 6 wood, loads of stone, some skeletons, body parts etc. This was also outside.

Using Phoebus' tileset and some modified init settings, no other mods to the game.

Uploaded the save folder to DFFD: http://dffd.wimbli.com/file.php?id=6443 [^]

The game should load up on the right level (top, outside). There are 3 points marked: a square to where it teleported before, the garbage dump, and a floor tile being deconstructed.

Edit: It actually teleported both the contents of the dump, and the previously teleported stuff (in the save the dwarves are still busy hauling the stuff back to the dump, from the previous teleport).

Also, the teleport with the deconstructed floor actually happens to where the deconstructor is standing, not to the deconstructed tile itself.

Edit2: I just realized that it must have also emptied the refuse stockpile the first time it happened. I was wondering why it was empty, only made the connection now.

2012-06-07 04:38   
Uploaded my save folder too: http://dffd.wimbli.com/file.php?id=6444 [^]
2012-06-07 04:43   
>> How could I demonstrates this bug? It needs a "before" and an "after". How could I save two times?

You backup the save by copying the region folder. It is located in <DFfolder>\data\save\.
The save from before the bug, which after load reliably replicates the bug would be best (and enough).

Thans Rafal99, file updated. Now just destroy the tower-cap wall to test the bug:
http://i.imgur.com/GwjM8.png [^]

I have disabled the wood hauling labor. It will make it easier to test.

Another bug: If you have a garbage dump zone set, some logs are dumped and destroyed (you can test it in my saved game).

2012-06-07 08:33   
(edited on: 2012-06-07 08:34)
Ok I tested your save http://dffd.wimbli.com/file.php?id=6444 [^]
And I confirm the bug.

If you load the save and deconstruct any wall then about 46-47 items gets teleported to where the deconstructing dwarf stood.
The items teleported included wood logs, vermin remains and even empty barrels.

Deconstructing more walls later causes various amount of items being teleported, usually the very same items or a subset of them are getting teleported every time.

Building a new wall from either wood or stone and then deconstructing it also causes the bug.

I noticed that most of your already built walls had its materials set to Dump or Forbid. No idea if this was the initial cause of the bug, but removing the dump and forbid designations from these wall materials didn't prevent the bug from happenning further.
(I had to build a chair and assign a bookkeeper to get accurate counts in Stocks screen, so I could view the materials from there)

2012-06-07 12:47   
Ahhh... this probably explains why there are half a dozen granite blocks in my caverns next to where I was walling off the cavern lake. I deconstructed the wall and ramp I was using to access the upper levels of the wall and only later noticed far more than 2 blocks on that tile.
2012-06-08 09:25   
I also have this same bug occurring when deconstructing walls. It was quite a shock when I noticed it, because the items that were relocated were locked inside sealed "cells" with no way in or out. I have uploaded a save to DFFD as well. The walls have been marked for deconstruction before save, so just unpause and watch the magic as the three nearby corpses and their equipment are moved out of their cells upon wall deconstruction:

http://dffd.wimbli.com/file.php?id=6453 [^]

(Oh, and I use no mods or utilities of any kind, strictly vanilla DF.)

2012-06-12 14:46   
(edited on: 2012-06-12 14:47)
Only using native DF 34.11 and DT, no tilesets, no utilities

I have a giant quantum stockpile of stone and a nearby legit stockpile of wood, and three times the quantum stockpile has been moved about 12 tiles and most if not all of the wood stockpile moved in the manner described above.

First two deconstructs were dolomite mine tracks, the third was a diorite door. I've only noticed this happening in the same Z-level.

2012-06-13 16:57   
I didn't realize it at the time, but this appears to have bit me as well. Changed my mind on where some surface walls were to be located and when some of the walls were deconstructed I noticed "extra" logs (wooden wall) where I expected to only see one. It does not happen every time for me, however, as I have just deconstructed a few wooden walls underground (working through an aquifer) without it happening.

v34.11 Phoebus, no mods unless Phoebus made them, and I don't believe his changes could account for this.
2012-06-17 21:57   
I just this happen in a new fort in vanilla 0.34.11.
It teleported about 20 dumped items from nearby garbage pile, and about 30 iron bars from nearby bars stockpile.

It seems to trigger this bug you need to deconstruct a wall near a pile of forbidden items, or near garbage dump zone.
2012-06-18 09:21   
In that case, "near" means "within (at least) 40 steps," because that's the distance from the nearest garbage dump or forbidden object that I have observed the behaviour.
2012-06-20 04:59   
Confirm that in my fortress. Deconstructing floor made half of bar stockpile teleport to one tile, as well as quantum pile of ore.

Also, dwarf deconstructing stairs from above gets hit by stone block that stars was made of. I think it has same nature.
2012-06-20 10:16   
>> Also, dwarf deconstructing stairs from above gets hit by stone block that stars was made of. I think it has same nature.

Intended behaviour, not related and not a bug.
2012-06-22 08:36   
(edited on: 2012-06-22 08:38)
Actually it was considered a bug before it was fixed, and it could become related if a dwarf deconstructs a stair above him- or herself and a whole stockpile comes crashing down on their head. The fix that causes the dwarf to place the deconstructed item at their feet wouldn't apply to teleporting objects, and you could end up with a real problem of deadly avalanches of stone while removing scaffolding.

Related to the bug: I had this going on in my fort, but the only thing being teleported was a single ocelot hair earring that I think came from a dead goblin. It wasn't dumped or forbidden at the time, and the last time it had been forbidden was after the goblin was killed a la 0000903

2012-06-22 09:20   
I just saw this bug in action, too. (Sorry, no save.)

I was setting up to test some melting, so I embarked on a volcano, and started building stone block floors over the lava, with holes for the smelter and forge. But I had the forge's hole in the wrong place, so I deconstructed a floor tile in the correct place. As soon as that happened, the contents of the stone block stockpile, and the contents of the tetrahedrite stockpile, were all teleported to a single point next to the deconstructed floor spot. I think it might have been the same spot the dwarf was standing on while deconstructing.

0.34.11: I was removing boulders from the path to the new trading depot, by first building walls on top of the boulders and then deconstructing the walls. When the walls were deconstructed, piles of forbidden junk from nearby weapon traps were teleported into the tile where the dwarf was standing.

I uploaded a movie demonstrating the bug, you can see the nearby items suddenly vanishing:
http://mkv25.net/dfma/movie-2450 [^]

Also an older save of the fortress, you can reproduce the bug with it (just remove the civilian alert first):
http://dffd.wimbli.com/file.php?id=6538 [^]

2012-06-22 12:11   
Hmm, now I wonder if this teleporting problem is caused by the fix for that block crashing on the head bug. It potentially could be incorrectly computing the subset of items that should be placed at dwarf's feet. I need to find time to finally investigate this :)
2012-06-23 03:04   
Yeah, there is a loop that vacuums up all on_ground items in the 16x16 block that contained the construction and places them in the tile of the unit. It's obviously missing a coordinate check to make it apply only to items in the construction tile.

More info on this one: Deconstructing two sections of wood wall about 60 tiles from my wood stockpile. 0.34.11 Phoebus, linux.

O1OO  O = unconstructed wall designation
+XXW  X = walls to be deconstructed
2W_W  W = constructed wall
+WWW  + = floor (grass), _ = channelled hole

1 is a floor tile where a new wall is designated to be built and Dwarf A was standing
2 is a floor tile where Dwarf B was standing

Dwarves A and B ran over to deconstruct the walls (Xs). Dwarf A (at 1) finished first, and the wood from the right hand X appeared in his tile as expected. A few seconds later Dwarf B finished tearing down the left X and when the wall disappeared, the logs at 1 disappeared as well. When I checked 2, which showed logs, using [k] it showed both sets of logs were present, even though there should have been one at each position (1 and 2).

2012-06-30 08:44   
Is there a known work-around for this bug, then? I can post my save as well, but it looks like we already have a number of demonstrative saves so it's probably not necessary. Phoebus, Therapist, Mac.
2012-07-02 05:05   
Reported a similar bug.

Was clearing soil of young saplings and shrubs by constructing floors and deconstructing them. Deconstructing the floors somehow teleported all the seeds barrels from nearby stockpiles as well as a Forgotten Beast corpse from the caverns. The caverns are sealed off from the fortress. The FB was killed by a tribe of batmen living there.
2012-07-04 07:16   
Since this is such a weird bug, and from the scale of changes currently being made it doesn't seem that there will be a new release any time soon, with some help from Quietust I've made binary patches that fix it.

Linux v0.34.11:
1) http://pastebin.com/DBHzubUg [^]
2) http://pastebin.com/PRDcnjeu [^]

Windows v0.34.11:
1) http://pastebin.com/SVCEU3N3 [^]
2) http://pastebin.com/Y8Br5hHU [^]

They fix the following problems with the code:

1) When the game intends to move items located in the tile of the construction to the tile of the unit in order to avoid bug 5907, it forgets to check the item coordinates, and ends up moving a whole 16x16 tile area worth of items.

2) In addition to that, due to the way it loops over the list of items, if there are multiple items on the down stair being deconstructed from below, up to 50% of them will still fall and injure the worker.

Expressed in C++, the combined change is from:

for (int i = 0; i < block->items.size(); i++) {
  item = findItemById(block->items[i])
  if (!item || !item->flags.on_ground)
  /* move item */


for (int i = block->items.size()-1; i >= 0; i--) {
  item = findItemById(block->items[i])
  if (!item || !item->flags.on_ground || item->pos != job->pos)
  /* move item */

Warning: beware of mistakes applying the patches, proceed with care, etc.
2012-07-09 07:06   
I've posted here before, but just wanted to note that whereas previously I had only seen this with items in garbage dumps or stockpiles, I just had some minecarts which had been moving(!) nearby teleport to a tile that I deconstructed some tracks from.

Uhm... As for the binary patches... Can someone share a download for this that's patched? I don't know what to do with all that text, but this bug is real annoying to me as well.

I have seen this with a constructed floor hosting an animal stockpile.

Constructed floor
designated animal stockpile
used p-->x to remove a portion of the animal stockpile
deconstructed floor where the animal stockpile was removed

Stuff still happens, blah. How do I apply the binary patches, exactly? Kinda forgot to tell us dude :(.

AG - your binary patch is not working with python v3 in windows. Results in syntax error. I had to:
- install python 2.7.4
- save the pastebin text as fix.dif
- save http://stalkr.net/files/ida/idadif.py [^]
- I put both files in my dwarf fortress folder
- executed the script using "idadif.py 'dwarf fortress.exe' fix.dif"

It appears to have patched correctly and objects no longer seem to be warping. I'll follow up in case I notice anything fishy going on.
