Summary0002473: Dwarves will walk across unbuilt/not-yet-constructed floors
DescriptionAs a part of my attempt to exterminate any elves that come near my fort, I surrounded my trade depot with walls, and rigged up an automated 'lock the elves in then drown them' system. After testing this, I found that because of the climate, the flooded area would freeze before I had a chance to drain it to retrieve the elf-loot. So I set some dwarves to build a roof over the area with floor tiles (b-C-f).

While watching them build, I noticed the masons pathing across about 20-25 squares of un-built floor tiles to start constructing on the opposite side.

In short: Dwarves observed pathing across floor tiles that do not yet exist in order to construct other tiles.
Steps To ReproduceBuild a square of wall, with an access (stairs). Shift up 1 z-level and designate the open area between the walls as a floor to be constructed (b-C-f). Observe as dwarves walk across this open space.

Sorry: 0000024:0000020-25 should be 20-25. My pretty picture in 'steps to reproduce' got eaten too.

Can you eliminate a varaible please, did they walk over the wall sections which are pathable?

No they did not path across the wall sections. They were walking across empty space.

It would be helpful to upload a save where a dwarf is currently standing on empty space. http://dffd.wimbli.com/ [^]

Was the space full of ice at that point?

My apologies for the late reply. I have been unable to reproduce this issue (though not for lack of trying). I believe we can either write this off as a screw-up on my part, or a once off. If I catch it happening again the first item of business will be getting a backup of the save though.

Sounds good. Feel free to reopen this if/when it shows up again.
