I've had this problem a few times since Saturday now. While building a mansion, i went from buy mode to build mode and the build mode panel disappeared(not sure if that's what it's called, but I'm referring to the panel next to the sledge hammer and blueprint panel that contains all the building features- walls, floors, etc.). None of the controls are working (walls up, walls down, sledge hammer, live mode, buy mode, etc.) When i click on an object in my house, a button pops up saying "Thumbnail Camera". When i click on doors specifically, it gives me an option that says "Add the ability to add triggers and add behaviors" and "lock". The game isn't frozen- It's just a glitch? I know how to shut the game down using Task Manager but i wanted to know if anyone else is facing this problem, or if there's any way to get out of it and save my game.
