There's another problem that hasn't been fixed and it most often occurs is that Sims throw a party but unable to attend it as the game says that the Sim is out for the moment. However, I found a workaround for the issue which had worked for me. I clicked on the house where the party was at, opened the console with Ctrl+Shift+C and entered resetsim (In the case for my game, it was Miles Forthright) to make the party thrower return to the house, I clicked on the house and now I can attend the party.
Just curious, other than the no click on Sim bug, has anyone enountered issues/bugs such as the daily party invites in Sims University?
