Whenever I add a stage, my fighter textures return to normal.

[Tynnan]

I've recently started to learn all of this stuff, so please bear with my noobyness.

  Whenever I successfully make a custom stage tab using a custom SSS, all of my fighter textures and models return to what they were originally. I've even used Mewtwo's stage expansion tool to see if i've done something wrong. Does anyone know the cause for this?
