I didn't know that was possible but no. I just started that save as a vanilla file not too long ago, completely starting over with a new Sims 4 folder. That caused me to redo all of their club selections all over again. My one sim had 221 perk points and the other had 100. Oh but my sims little bro was able to max out the level of people allowed in the club but I still had the 2 open slot availability. I didn't add anyone. Other than that, not sure what else you mean or what it could've been. I literally switched households as I mentioned above and the ability to save worked but I'm concerned if that could cause possible corruption of my game. I'd rather revert to an older save than have to start a vanilla game again if that's the case but idk what the case is. I also played for 2 sim days under that household I switched to and I was able to save fine after going to the detective career with that sim and playing that whole scenario -_- I noticed that inmates disappeared after coming back from an outing though. I thought they fixed that as well. I suppose that glitch is back again.
