CnC has anime characters from VNs, and if it were the powers that would have been mentioned. More likely it's that you didn't write as good a history as you thought.

Most VN players I know pick one route to app from rather than detailing every one of them, so I could see how that would confuse an app mod. More often when a history is given revisions, from what I've seen, it's because the apper spends more time detailing the story in general instead of explaining their character's part in that story.
