A rather large number of inns are lacking the global variables on their doors. This is what allows the player to "own" the room during the time they rent it.

Normally, this isn't an issue since the door is automatically unlocked when rented. However, if the player decides to lock and unlock the door using magic while they are staying there, them unlocking it will cause them to commit a crime, even though they have reserved the room. It also helps with mods being able to elaborate on this functionality.
