Hey Lücìus,
Customer Support is unable to refresh or update the armory manually, I’m afraid.
That being said, this kind of issue can happen every so often, and may affect a character or a guild. Don’t worry though, it usually resolves itself automatically during the weekly maintenance, on Wednesdays (this is (in parts) what the maintenance is for).
If the Armory didn’t refresh for your guild this morning, please give it some more time, and it should eventually catch up soon.
Thank you for your patience, and good luck with the guild!
