As seen in the photo, whilst playing on creepy crypt a friend and I were previously on the other side of the wall and the travel button was present on screen so we both pressed it. When doing so, we left creepy crypt for the creeper woods and upon entering the door we just came from, we return to this wall blocking our path back through the creepy crypts. There's no way to get around this that we found, so we had to quit after finding all 20 chests and 4/5 secrets!
