True, it can be difficult to keep track of stuff, but on the other hand, it's their job to be professional, there's always something like wikis, character discussions, or hell, talk with the fans, ask the questions about powers and consistent feats, and if making an official account is not an option (I can see it being embarassing for a writter to ask fans about this kind of ****), they can always just make a fake account, create a thread, ask a question, then check later for the replies, they have a lot of options, and if they don't know something there's no excuse to not try to find an information.
