Fixes #4514

Created by: Exxion

I don't like the unimaginative title, but there's not much more to say. I have no idea at all how that happened in the first place.

As this tile is now identical to another one, the "correct" way to do this would have been to remove the line defining this tile completely and change the map layout to include that other tile where this one is rather than just edit this tile, but that would have increased the probability of conflicts almost infinitely and it'll probably fix itself next time someone uses Dream Maker and the map merger to edit the map anyway.

Well apparently titles don't work for that so fixes #4514 (closed).
