Collection breaking bug

[Arkena]

Just a heads up, at some point in the main story you get the key of admittance at the top of hogwarts tower; if you're there during the quest and go back to use the key on the door the 15 second countdown will start and you can't escape the door opening scene, causing a gameover. If you retry or abandon quest and continue on the door remains locked and the key will be gone forever, meaning you won't be able to get the field guide or chest in the room.

You can get up there easy on a broom.
