Return of Reckoning

Already filed a bug report on this, but maybe this is a known issue that has a fix, so here it is. We formed ou guild the first time last week, and since then, it has dissappeared twice, today being the second time. The first time we had to actually gather 6 ppl again and create it again. Until this afternoon, the guild was ok. Now I logon about an hour ago, and its not there anymore. I confirmed with other players, no one is in a guild anymore.

Guid Name: hCore
Level 4 or 6 (cannot remember exactly)
Guild Leader: Truekandur
Guild members: Tomate, Morvius, Arquimago, Adoky, Barbeiro (and others I can't recall now)
