NPC Events happening through Walls

This isn't really a big deal because I can't really think of way this would effect anyone but NPCs like masters or even boss rooms with shaper can begin their event or dialogue when you are near a wall adjacent to the one the NPC is in.

Even if getting to that room would actually require you to travel some distant, in some cases I wasn't even close to the boss room but could see it on the map, and shaper would pop up saying "bwah bawh bwah little mouse" and the screen would freeze up indicating the boss change but I wasn't even close to the room.
