Texture Previews Don't Match Textures

I don’t know how it is for the other tilesets, but the AiurTempleJungle’s tileset doesn’t show the correct preview for the tile you’re selecting. It makes brushing a headache.

If you mean it shows an image like it, but with missing shade or color, then yes it does this. But you may switch textures there, then test in-game for the visuals results.
