I've fixed the slot 25 in the PSP stage, it wasn't configured in the xmlb. It overlaps a bit with Black Widow, but whatever... what matters is now I have all the next gen content working properly, so tomorrow I will upload the patch. Thanks for your help, Teancum!
One more thing, I also used the Moon Knight PSP mannequin. It was hidden in the characters_heads_ng.fb file.
