Can't join tribe.
Invitation not received when given.
Just left the tribe I'd been in this last week to rejoin my old one. Even though I'm being invited (by my alt, with which I've done this many times before), I don't receive anything at all on the invited character (not even "can't join for another xx minutes", which isn't the case, since I have't joined any other tribe within 30 minutes prior).
The timing is this issue is extremely aggravating.
