One misconception I think a lot of new users (and maybe some old users too) fall for is that getting a question flagged and closed is inherently a bad thing, when it’s really not. Yeah, we understand that you didn’t realize it was already asked, otherwise you probably wouldn’t have re-asked it, but the information you’re looking for is already available on another question, so there’s no reason to keep the new one up.
Of course, if the thread we link doesn’t answer your question, be sure to leave a comment telling us why. If it’s just that the old question is missing information on new Gens, we’ll probably just add that to the old answer, since we like to keep all the information in one place. But there are times where we’ll reopen your question.
