Game-stopping bug at "Beasts" after "Stern Crane"

[WaffleKing]

I've run into a massive bug that prevents me from completing the game.

In the level "Beasts", after turning on the Stern Crane in the Mental Echo, instead of going back to where the body was, I GET TELEPORTED INTO THE STERN CRANE. When I try to get back to the catwalk room, I'm locked out because the door no longer works.

I've tried restarting from an earlier save, but I still get the same issue.

Is there any solution for this? I'd prefer something besides using debug mode to noclip through the door, as that could cause scripting issues that would further mess up the game later on.

BTW, is there any way to delete autosaves? My autosave list is filling up with a dozen autosaves at the exact same spot because the game autosaves every time I try to get past this bug.
