The TV guy didn't even appear for me at the end.
I just flipped the last switch before pressing the button. After that I just walked straight to the lift.
Thanks for letting me know! I've seen this happen to a YouTuber as well, and I honestly have no clue what causes it. I don't really have any plans to update the game right now, but if I end up figuring out what causes this bug, I will definitely wrap it up with a few other fixes and update it.
Thank you!
