'See what's happening' Glitch

I've recently moved myself into a game (a couple and to children) and as soon as it starts one of my sims becomes embarrassed because their 'privacy has been invaded' and the rest of my sims are embarrassed because they have 'walked in on them'. After this they won't do what I tell them to do (especially not interact with others), it'll be in their queue for ages and then cancel when they are about to do it. They'll also constantly 'See what's happening' and I don't know why.

I have a bit of custom content for cas but I've had them for ages and this has never happened in any of my other games using the same cc.
