there are a lot of bugs in this game. ill try to make a list of all the bugs I've found SO FAR in the game:
1: employees stay in one spot and don't move
2: employees dissapear completely (as in they dont come back and you cant do anything about it)
3: you cant always place things where you want to place them (I.E.: placing offices near elevator shafts)
4: the game freezes and becomes unresponsive
i havent found any other glitches/bugs but the game is very enjoyable (when it doesnt freeze)
