Hey, I'm totally sorry about not getting back to you about this.
I'm not exactly sure what you mean? From what I can in the history page for Eden Assassin's main article, the changes you made are definitely logged. I definitely moved them to the sub article more or less unchanged.
The only edits I explicitly deleted from the article were from two users who added fan art and unconfirmed stats information onto the page (or at the very least stats information I couldn't find a verified source for).
Unless you're referring to that, I don't think any of the information you wrote was erased from the article by my prior actions. If they were, that'd be some kind've hiccup on Wikia's end of things.
