What switches are they?
Also, copy my game remove scripts no change, that could mean, you have an event, maybe common, or something else.
Try an empty game, nothing in it, un touched. See what happens.
You have to start some where, and might as well make it the beginning.
1st step, clean game.
2nd, add scripts to clean game, one by one.
3rd, go through all your common events
4th go through all your events, let's hope you don't have to do this, XD.
usually 1 and 2 fix it for me. I thinK I have a script that can search switches and variables being used. I'll look it up.
