I be affected by this bug, Partners in Crime remains though
Also if I may note, if you are affected, all you need to do is try changing servers, or TP to someone. Kinda like "refresh" the game, keep trying this, it should fix itself.
Something else that happens is if you are affected, and your guild does come back, and you try chatting, it takes a good 5 minutes for it to come up.
My advice is that you whisper to members, dont use guild chat untill this problem is resolved.
