Well... This bug have a little story behin it.
Day before the end, our custom ai has hard broke (It was think that door is a wall for some reason), so we just used standard one. And for some reasons, this ai sometimes think that's the wall is a floor xD I wanted to fix it, but forgot to try... XD Bth it's seems like we change one problem on a opposite one :/ Hmmm <' -' >
And Btw, Thank for playing!
