While recompiling your MRS your Textures got corrupted.
Did you Encrypt your files?
That happens mostly with either encryption or insane big textures.
Try to recompile your File some times and try again.
Also try Reducing your Textures Size to 512x512 or 1024x1024.
Well, i just compiled it and didnt encrypt it or something. And those textures should be alright since it's just a straight copy from Island.mrs I also tried to make one on the boat in the map Island, and some textures appeared and some of them didnt. So i quess the texture size is to big for a login.mrs?
