Title. After going around and killing the Graveyard enemies and getting the crossbow I found out I can jump on the locked building's roof. The game however freezes once I reach the edge of the roof and the games stays there with the loading icon spinning the player unable to move and I cannot do anything. I can only open the map/inventory overlays. Any help?

I'm afraid I don't have any useful advice in this situation, but, in general, note that this game has a lot of bugs and frequently freezes. Saving regularly is very strongly advised.
