I have this issue.
Yesterday, maybe it was the night before, I had a message of "you had an intermittent loss of connection to the clan server." something to that effect... Shortly thereafter? I can no longer see the clan, it just shows as 0 players online, before the N button showed me the looking for clan thing, however my name shows I am in a clan. At least now it shows I am in one, but always shows 0 players online, even though that's not the case.
I just tried repairing the game, I don't think restarting my computer will fix it, but I am going to do that. Any ideas?

This is weird.
Restarted, repaired, didn't work.
LEFT the clan, got invited back... I can see the roster, news, and clan chat now... wtf?
