(alpha 9 release 256 (x64)) Construction Bug after load

Problem: LUA runtime error when attempting to edit a slab construction, it allows me 2 actions before the error shows up.

Expected result: Game continues after load like its supposed to.

Actual result: get a lua runtime error involving brushes and the construction disappears but is still there sorta, hard to explain so here be screenshots.


Intel I5-3570k cpu @ 3.40GHz

GeForce GTX 550 Ti

So far the only thing I’ve figured out to get around it is just have my hearthlings build what i already had set up and then worry about finishing my design when they are done.

Update: this workaround didnt work because of another bug where my hearthlings are sitting everywhere.
