[RESOLVED NOT A BUG] Bug with wall and floors

Hello!

If you climb to the floor above, then part of the wall of the lower floor disappears:

Hello - thanks for the report!
As there is no saved game file attached, i can only assume from the screenshot, that it looks like there are no foundations built on the second floor in respective area - try to place them over that area and then modifiy it as you wish.

Or, please, uplaod a saved game file and i'll take a closer look at it

Map

I think my map in many thread )))

Well - this is actually not a bug - you have missing foundations on the second level, right above that area.
