Here are the ADTs (in noggit) that the tileset they use I'm looking to swap are located.

So pre-cataclysm.. why were you looking in MoP then? XD :lol:
Your screenshot on the editor says tile 30 46 , so if one were to simply drag and drop the ADT into a hex editor, or text editor and do a search for .blp , they'd get this list:
TilesetWetlandsWetlandsdirtmoss01.blp
TilesetWetlandsWetlandsGrassDark02.blp
TilesetWetlandsWetlandsGrassDark01.blp
The other screenshot, you had highlighted 36 49, dragged that into a text editor as well and here's that list:
TilesetWestwoodAlphaWestFallLeaf.blp
TilesetRedRidgeRedridgeGrassDirtBase.blp
TilesetRedRidgeRedridgeDirtBase.blp
TilesetRedRidgeRedridgeRockBase.blp
TilesetRedRidgeRedridgeRockRoadBase.blp
TilesetSwamp of SorrowsSwampSorrowsMuckdark02.blp
^ see how that works? I'm sure there's a way to do it through Noggit, but I'm not a World Builder so naturally I'm doing it through tinkerer methods XD.
