I've noticed before that people who made an account months ago (at least over 11 weeks ago), sometimes still show up as being 11. I mean, I went to all users on the Marauder's Map, and there was someone who had signed up 4 months ago, so that is over 1 WoP year, which means they should have aged up to 12. They are inactive, I don't know if that contributes.
They have not passed to the second year (which is, of course, because they are inactive). When I went to their profile and hovered my cursor over their name there, it did say 12 years old.
