I recovered the game last night & was able to regain most of the progress we'd previously made. Haven't tried the meet & greet again yet. I'll try it at his home next time & see how that works.I'll also make sure I save the game just before it starts. I'm relieved to find that aI'm not the only person who has a problem.
Have you also had issues with the awards night? My Sim needs to win an award for his aspiration but when we went to the awards ceremony, although I got a message saying he'd won an award & it was in his inventory it wasn't there & he didn't get the aspiration points.
