@4llen11 Did you also remove ANY mods/cc you have and test with an empty mods folder ?
How big is your save game ?
But you have 80 Sims in your whole game not a single household ? Just making sure cause you said you had 80 Sims in one household which seems a lot and is only possible with mods.
@4llen11 So sorry, missed that. I'll let you know.
EDIT: So, Did you put any of your mods back ? Especially the ones that let you have that many Sims in one household ? If you load the save with no mods, the game needs to remove all the extra Sims (it does so when you load the household or go to CAS) and I think that just overwhelms the game. I would suggest waiting till all the mods you are using are updated and try again then. Play a new save until then.
