Some additional information:
- Movies in-game work just fine. It's only the title movie that bugs out.
- I have a skip movie hotkey I scripted into my game to skip in-game movies. A while back, I would get the same error if I skipped things too fast. I fixed it by adding the "currentTime" line. Maybe that can help get you on the right track for why it's happening? Maybe something is happening too fast?
I'm still open to sending you my exported project if that'd help you investigate.
