I activated my gold account medal and I've got everything except my icon. I've used some of the things like the auto pricer and 10 extra quests, so I know the account is actually working.

The first time I got GA, it only took a couple hours. I activated mine about 8 or so hours ago and I still don't have the icon.

Should I be worried or is it normal to take some time?

I just looked at your page and it's in there now. :)

It can take up to 24 hours for the icon to be changed. You can still use your GA, it's only the icon. It'll change soon.
