|0004372||Dwarf Fortress||Dwarf Mode -- Jobs, Building Construction and Destruction||public||2011-03-28 01:56||2015-12-10 11:48|
|Assigned To||Toady One|
|Target Version||Fixed in Version||0.42.03|
|Summary||0004372: occasionally get negative distance value for materials for constructions|
|Description||When constructing buildings, particularly walls, I sometimes get a negative distance value for some materials. These materials are listed first, and usually in the -60,000 to -70,000 range. The distance doesn't scale properly, moving one square to build the next wall produces a difference of several hundred or more. When selecting that material the building is suspended when a dwarf attempts to build it.|
When hitting 'x' the expand the selection I can still select an individual item with a positive value, though the negative value items show up first. I can forbid the negative value items in this menu to get past this.
I'm using Phoebus' graphic set version 24.00. In case it's caused by that.
|Steps To Reproduce||0.40.24: See 0004372:0033030|
|Tags||No tags attached.|
Reminder sent to: Drawde
It would be extremely helpful to upload a save demonstrating this problem to http://dffd.wimbli.com/ [^]
|Is it possible that you are constructing things from ice? It happened for me after melting of mined ice.|
Done, under "Negative material distance" in the bugged saves section.
I listed the steps I took to duplicate it. I had to remove the stairs in a room, the only way into it, and then tried rebuilding the stairs there. As I said, it doesn't always show up. But I think it's caused when some of the material is unreachable, but locked doors didn't seem to be enough to cause it.
|For ease of retrieval you can also link the file, like so: http://dffd.wimbli.com/file.php?id=4069 [^]|
I had it happen once in relation to smoke blocking access. I forget the exact circumstances, but I think it happened when I tried to build something in an area that was covered by smoke. Or at least the smoke was either blocking the pathing or was blocking materials, don't remember exactly.
I know it's not much to go on, but it's a possible lead to reproducing it.
|I've encountered this in 40.10 and have uploaded a save to http://dffd.wimbli.com/file.php?id=9557. [^] Smoke may have been a factor here as well--I had just had a dwarf incinerated by a fire imp nearby. Also, I noticed that each time I escaped from the selection menu and then reentered it, the distance would increase by an additional 1250000.

Confirmed in v0.40.24. This bug appears to occur when the path to a material is "soft invalidated", and resolve itself when the game is reloaded (and paths presumably recalculated).
A reproducing scenario:
designate one tile for channeling per z-level in a 2x1 area, alternating which tile on each z-level, such that each subsequent z-level "breaks" the ramp on the prior z-level.
wait for your miner to dig down and produce some boulders
designate a construction on the surface, and note the recently-produced boulders appear at the top of the list with negative distance.

|Cool - I also got it to happen with channels. Thanks for the reproducible procedure. There might be other configurations that cause this to happen, or something with water or cave-ins or whatever, but this is probably the main culprit, so I'll mark it off until we see it again.|
