"sims 3 has stopped working"

Sometimes I just have to step back and say, "Okay, the game wins this one" when it puts up more of a fight than I am willing to engage it in order to get something done. Just a thought, if you have a saved game already where you have altered those tower buildings to how you like them, could you not copy those lots down to the bin and replace the ones in your current game with the already fireplaced copies or does that not work either?

But I can still try to do what you are attempting in-game at some point this weekend just to see what happens on my end.
