You are far more likely to encounter the crash if you pause the game while dropping peeps. As I mentioned in my earlier post, it is a bug in the game that is related to the way villagers shake their heads, and we will be issuing a game update at some point to correct this and several other issues. Changing settings in Windows will not affect this issue, but you can greatly reduce or eliminate the crash by not pausing the game to drop villagers on a task.
