I read about something similar to this in another thread, but not exactly the same, as their Sim was able to still perform other gigs. My Sim was singing in a big venue, and typically after the allotted 3 hours the show will automatically end. Well, that never happened... she just kept singing for hours and hours. I tried to X out of her 'Perform' action, but it wouldn't let me. It also wouldn't let me click on anything, inside or outside the venue (and just with that Sim - other Sims were able to function normally). Finally I just reset her, but the gig is still on the schedule as not completed - and it won't let her do any other gigs on her schedule. The original one still shows up on the map as the one she has to go to, but when I had her go 'set up the stage,' it set it up for a split second and then the action disappeared. Not sure if this is a glitch or not, or how to go about fixing it. Anyone else experience this and know a fix?
