Subject: [PATCH] Fix for actors / crawlspaces / doors not loading after
 loading a savestate (#6838)

Fixes an issue where actors do not load properly after creating a savestate and then going to either a new scene or loading a different area of the map (graveyard near shadow -> main section of graveyard dampes door is missing after loading again.)
