I'm having issues with the events. The wedding event for my founder and her fiance bugged out. It appeared that I was getting credit for the initial criteria because it went to silver but the items didn't tick off the list (like the get married even). So since they didn't tick off, the new criteria never popped up so I couldn't get a gold. Now I'm doing a birthday party for the spouse and the Have an Adult Make a Toast isn't working. My founder had a drink and tried Make Toast about three times. All three times the animations completed and it looked good but no completion. I hope the dates work. Haven't done them yet. The only event I've managed to get to work properly so far is the House Party.
Edit: The next day was my Founder's birthday and I hosted it on the home lot and it went off without a hitch. But it had different criteria and the Make Toast didn't come up.
