The locker bug has to be patched, it's unplayable, even in the newest version where it was suppoed to actually be fixed
its kinda playable just go to the door that is after you and then look behind you would probably be in the school again but you will still see this shadow effect.
and there is a way to fix this? because its hard to see where are you going.
I'm sorry but I currently don't know how to fix. That's all I know about this bug.
That happened to me too LOL
