I tried to build a stone building for my mason. I was not able to do anything in game but move around with the arrow keys.
I tried building the same building later, but with a wooden roof and that worked better. But I still got lots of errors near the end of the building.
Had to revert to an older save before I started the stone building. Could only build a wooden building.
hmm… im pretty sure there are some reports about stone building parts wont be built or something like that.
