I'm having some issues with the first map - when Wheatley is supposed to come into the room on the rail, he instead moves off to the right (when facing the door) and remains out of sight for the rest of the sequence. The door in the ceiling does animate correctly, but the small rail section at the end appears to also be off in the same direction. Additionally, when the room starts moving, I am left behind on the floor (the character model doesn't appear to be affected by the room moving at all). The sequence plays out in it's entirety, but I am softlocked at the end (as I am still on the ground, the pause menu is invisible, and there's no way to continue to the next map)

Any suggestions as to what could be causing this and/or how to fix it?
