I've recently downloaded City Living and ever since my sims have not been able to move on to actions in their queue but instead get stuck. Even when I reset them they stand still with an action queued up but never actually dropping down for them to act on it. The only exception is things they can do themselves such as showering or sitting, but when they are sitting they can't move onto an action they're meant to do during like talking or making a move, they just freeze with the sittting action lit up.
I have deleted every mod that was detected to have any issue, I restarted the game multiple times, and nothing is fixing the issue
