Probably NOT harmless. Best case, you applied Map Mishap followed by Phoenix Chest, in which case everything's fine. Moderate case, you applied only Map Mishap, in which case there's probably a side effect that makes the chest appear open before Locke actually opens it. Worst case, you applied Phoenix Chest and then Map Mishap and broke the universe.
Don't worry, it shouldn't be too hard to fix. I just need to remove that one change from Map Mishap. But while I'm at it, I can probably reduce the size of the Phoenix Chest fix by a byte or two as well.

Well, that sucks.

And I couldn't find Morph Mayhem's topic for some reason. ;P
That's because Morph Mayhem was one of the patches released for my first anniversary.
