Since robby updated the game quite a lot I have decided to return and play a bit more since spring break is right around the corner and as soon as I got on I opened up the Map (Was at goo dungeon) and a piece of the ledge area and swinging axe cuts onto the map.
Before the update I have never experience this but I think it probably has something to do with textures
(The new mushroom houses look pretty good btw)
Nothing Game Breaking just a small visual bug.
