There are several things that you can try, most of them are collected in this thread:

Can you try them and tell us if they worked for you, please?
Thank you so much for responding! Come to find out I had accidentally left a mod in my mods folder. I thought I had taken them all out. So apparently, this one mod is the problem. The other mods work fine with everything. I just take this out now when there is a simfest or if my sim performs. My sim no longer teleports home while performing. And I can see the simfests now and they are awesome. Thanks :D
What was the "one mod" causing the issue?
@SpaceMonkey907-2 It's unlikely that you'll get a reply from anyone else in this thread several years later. But if you have an issue now, you can open your own thread (or add to the one you started), and I'll try to help. Showtime careers can still be a bit glitchy, with or without mods, but most issues should be fixable.
