Time/Sim freezes while environment still moves

This is all my older sims saves that this is happening in. It takes forever to load my family but I do get to play. First day and night goes really well, and the second day even is fine. Then the second night and right after midnight time stops moving, my sims are also standing still and I have to force quit the game. New saves don´t do this. I have played with mods and without mods. I have tried recovering saves that I have before the new update but nothing helps. All my old saves are broken. I updated the game and took all my mods and saves away from the folders. This is really frustrating.
