I remember posting this issue on the vs forum, but I seem to have gotten the blank memory bug in real life and can't remember what the solution was. Since that thread is obviously not on that site anymore, I have to embarrass myself by asking the question again.
In a certain room of my house, all sims were jumping up in "shock" at a particular lamp. The toddler was "crying softly" over it. I thought the lamp was rather pretty, so I was insulted by their reactions, but I deleted it, anyway. The sims were then jumping in shock over each other. Repeatedly and randomly. This occurs only in that room, nowhere else in the house. I have the FFS Lot debugger, but there were no "out of this world entities", or however you put it. Or at least the option didn't show up in the menu. So...what do I do, again?
