Can't Use Theater During Show Times

For a little while now, my theater becomes unusable whenever a show starts. Before a show starts I have all the options pop up like normal when I click on it. As soon as the show starts it won't even let me click on it. All I can do is hover over it and have it tell me that a show is in progress. I can't do anything with the theater until the show is over. My Sims can't see any shows because of it, nor hold concerts if they're in the Music career.

I do have some mods installed, but I've had them installed for a long time and they've never interfered with the theater before. Besides Dragon Valley, I haven't installed anything new that would cause the issue. It's only the theater that's having the problem. It happens in old worlds and new worlds. I've gone through my files, but I can't find anything that might be the culprit. I'm not sure what to do at this point.
