Interaction pie not showing up?

I can't interact with another sim. No matter how much I click on them, it doesn't work. However, this is only after a minute or two after starting the game (or after already having done one interaction); it works fine in the beginning, but then it stops. I've tried deleting the local cache while testing the mods, but it doesn't work. I've also tried leveling up the singing skill as a last ditch effort, but that also doesn't work. The only interaction that does work is if I shift + click to bring up the cheat pie.
