Happening to me as well. Guild bug again as well as bugged in trying to make a party.
Anet since you have decided to release all this wonderful new content so fast, the game has slowly just slid into a cess pool of bugged out problems. How about you slow it down and make sure the content is not going to bug stuff out. TA is so bugged from the Aetherblade changes its not even funny. And how about adding in some of the simpler requests your player base has been begging for. Still missing some simple things that should have been migrated over from GW1, like the ability to watch people after dying, or a Last Active list in the Guild Roster. Simple things that should be a no brainer. :/
