No worries! We've all done the same from time to time! I assume you are looking forward to the new skin, me too!
I mean my Pixie Queen is still O2 (lol kept her there so i can still craft power of love, they really need to fix that so you can craft an item without having to find it on a hero- but that's another topic.)but the skin is cool on its own, and the avatar should be too!
