I'm on Destromath-US, and am having this issue. I'm not receiving an error, but my pets are simply not updating. I'll check the Armory to see if it has the updated information... If not, I think I will post on the BattleNet forums to ensure Blizzard is aware.

@Doobjanka -- Thanks! I just sent a Battle Tag invite request to you~ Drycoff

I'm also on the Destromath-US server, so this would help out a lot!
