I created a guild Avalanché [Elit] @ Far Shiverpeaks. Since tuesday, members that log in are not seeing the guild at all, it looks to them as they are not members of a guild. The few players that had not logged out in a while could still see the same players online in the guild roster though.
As a guild master I had the same problem, I could not see any resemblance of being in a guild since yesterday. As of wednesday, no one can see the guild and we start to wonder if it is still there.
