Proposals not working and other glitches

I just updated my game today. I want my sim to propose, but there's no proposal option. Their relationship is maxed out with best friends, totally in love, and  nothing except Join Household, which I don't want.

Also, Sim has had to go outside the house and back in in order to sleep, otherwise she gets up and won't stay in bed. Same with the bathroom.  It's being very glitchy and annoying with other weird things too, like stopping in the middle of cooking and I have to tell her to resume.
