I'll explain to you what's happening.. In mapmaker, i can get spy territory working with a quick fix of renaming my terrain mask. Clearly, you can see that it's working here:

so CLEARLY the game is reading everything correctly.. or so you'd think, right? right.
Now.. after I get this working, I save the map, and export it. Everything's great.. right? right.
Now I go into multiplayer.. and this is what happens:

Now.. if you look at the minimap, you can clearly see the HEIGHTMAP is the same.. but for whatever reason, the game isn't reading THAT one.. it's reading an old one that I don't even have anymore. Also you can see, the textures went back to sand as well. This is my problem.. and this is something I have NO idea how to fix. My guess is that my game isn't overwriting my .FHZ file.. and so i'm going to try deleting it all together and starting with a fresh one. Pray that it works.. and if it does, you guys will get this download.
