If I remember correctly, Treasure Maps are usually deleted once you find the treasure they belong to.

So I guess the map still existing is a bug. One capable of being abused if people were able to find really, really gullible people to pawn 'Fake Maps' onto.

It's probably worth fixing before something like that happens, at least, although I don't think most people bother buying/selling Treasure Maps enough for this to be worth someone's time to exploit anyway.
