Crashout when making changes in genealogy

Hi, 

After the update I noticed 2 things that go horribly wrong when playing the Sims 4.

1. because my families comprise of over 14 generations it takes forever to load into the game and play it (I didn't have that problem before, everything, mostly, went smoothly)
2. When I make changes in genealogy, e.g. my sims marry, the game crashes but it looks like that: time stops but at the same time Sims do the same thing that they were doing before crash forever (as if they are locked in one moment) - for example my sim was being burned and it never stopped. At the same time it looks as if time passes as I started playing during night and then there was sunrise.
3. Those things never happened before 3rd February update.
4. There may be other things but it is impossible to play right now for me.
