I had added two custom costumes for Fox, then later tried to remove one. The first costume file, PlFxPg.dat, no longer exists, and the stock icon and CSP I added are both gone. However, the slot still appears in game and in mexTool, no matter how many times I try to delete it. MexTool doesn't throw an error, it just acts like it's deleted until I save and reopen the iso or filesystem. It also steals the stock icon and CSP from the second skin I added, PlFxSk.dat. The result is a costume slot that looks like the costume I still want to have, PlFxSk, but crashes the game when selected, and a second costume slot that functions as PlFxSk but has no stock icon or CSP. All traces of the "deleted" costume, PlFxPg, are gone, except for the costume slot that is still trying to point to the non-existent dat file.
