Also experiencing the issue with an event bar and timer popping up on screen and when hovering over it, I get the (your Sim) is not participating in this event, but it does not mention if I can do something to participate or whatever.
If my sim is not participating, then why am I getting the event bar and timer? If I'm not participating and have no option to actually participate, I don't need to see it.
As for the thing when being asked on dates...if there is no goals showing, than why should I still reach the goals. If I need to reach goals for an event (whether I initiate or an NPC does), I should see the goals I need to reach, plain and simple. Can't expect people to just guess as to what is expected of them.
I have also experienced during a birthday party my sim was throwing that goals are not registered as reached even when they are. I had a three sim household and the task was to have 3 sims listen to the same music. I got them all to listen to the same music at the same time (was even comming out of the same speaker for all 3, but the goal just said that one sim was listening and not 3.
Guess EA needs to look at the social system, because some things are obviously not as they should be.
All these issues started for me after running the latest patch and installing City Life (which for me was on the same day).
I have no mods.
