Re: Social events menu messed up
This really looks like something an outdated mod would cause. I had something similar happen and it was an outdated mod that caused it.
So to make sure, you need to test in a save without mods and cc. To do that, move your current The Sims 4 folder somewhere safe. On your desktop, or somewhere else outside the Electronics Arts folder and start a new game. That will create a new The Sims 4 folder. Create the new sim, put them on a lot and start any event where you have seen it happen. If the issue doesn't happen, then shut down and copy just the mods folder over to the new game and restart and try the event again. If it come back, then it is certainly a mod or cc item causing it and you will need to go through your mods folder to find the culprit. Depending on how many mods and cc you have, it can take a while. I would start with the mods first though and make sure you have the latest updated version of those you use. Once you find and replace or delete what it was, then move your original folder back and give it a try.
Tbh, this looks like something an outdated UI Cheats would cause. That's what it was when it happened to me. So if you use that one, try that first. It was last updated early this month and the current version has been cleared to be ok with the last patch. So get the updated version and try that. If it doesn't fix it, then keep trying until you find what is causing it. You probably ought to do it testing one mod at the time. You could also try doing it via the 50/50 method to help narrow it down if you use a lot of mods and cc.
If none of that works, come back and let us know and we can try some other things. If it does work, then come back and let us know too.
Hope this helps.
