The bug happens sometimes when entering and exiting interior scenes. It's not very consistent but it can get a bit annoying sometimes. EDIT: There's also another bug that can happen when you enter a scene while running that forces you into an Always Run sort of mode.
I was doing the Hospital because I actually couldn't enter it without lagging in the public build (Which is weird because I have a lot of other, more graphically challenging games for my rig that it has FAR less trouble with) and I decided to cheese the Safe in the officer where you get the office ID and I noticed that after reloading the ID doesn't respawn unless you return to the main menu and then load back in. But anyway some items seem to do that, also so do doors I thinks? Because I had to exit and redo several earlier parts to get back to the vents and then leave so stuff like that may need testing in the future to prevent people from getting softlocked because a door that should be open was instead closed.
Ah, okay that does answer my question.
