I'm currently stuck in the same area (accidentally rolled back when I was supposed to check on Odette, now I can't do anything), and this didn't work. I tried *gamedir*/game/scripts/locks and *gamedir*/game/scripts/locks;, neither of which work. I know this is a couple-year-old post, but you'd probably know more about this than I would.
It keeps creating an .rpyc file which causes the game to crash.
EDIT 1: Map is greyed out, and I'm stuck where I'm at. Rolling back further doesn't help either, since I'd be stuck at the school. Any way you could forcefully unlock the map?
