Not sure if this is a bug. I noticed a couple of locations with straight line paths. These paths however are blocked with those 5 blocks (i.e when you enter the room, there is a path on the other side of those five blocks that you need to cross in order to reach). Now since I mapped out all the possible places I can reach on the first floor in Crypt 4 from the entrance, the paths that are blocked seemed to lead to new places where they can't be reached from any other alternate path. (The reason I think they would be leading to new places is because at location (10n, 4w) the path is blocked in the middle but the top and bottom of the path can be reached via different routes). Are those new places suppose to be reached later in Crypt or are they intended to be like that or they should be dead ends instead? These locations are at (20n, 12w) , (8n, 3w) , (4n, 1w), (9n, 12w), (7n, 12w), (10n, 11w), (20n, 12w), (20n, 14w)
