Using the architect ability from mechanic tree seems to end most of times with shaman crash. Little misplace or wrong object will simply crash.

Define "crash." Dos the game crash for you, everyone in the room, or what?

ETA- Actually seems Fastyboi explained it in another thread. Disregard.

I had the same problem now for 4 times

It does only crash for me (as I'm shaman). It looks lIke I just lag out of the game right after skill is used.

same problem for me i had it about 7/8 times and you dont get your skill points :/
