Here's part of the email I got form Skuzzy about the Spit I's -
"Kevin, I have some bad news about all the Spitfire I skins. There is a bug in the game, which precludes us from accepting Spitfire I skins right now.
All of your skins are approved, but we need to make a fix before we can release them. It has to do with the naming convention. It conflicts with the default skins of the spit14 and spit16.
Once we get that fixed, I will add your Spitfire I skins."
So once they have it resolved, we'll get them.
