I've started a new save with the same family in the same lot and the issue seems to be gone, so somehow the issue appears to be isolated to that specific save. Thankfully the game is playable in the new save but I worry that this could happen again. I'm going to reinstall my mods and see how it goes.
Nope, nothing popped up yet. So far so good, played a few hours yesterday and didn't encounter it again but I am prone to making new saves pretty regularly when I get bored so I'll be interested to see if it happens again. I did get another glitch during my gameplay where my sim just wouldn't do any queued actions and the time kept changing forward and back depending on the ff speed but going in and out of manage world seemed to sort that.
