I haven't gotten to the group part of the main story yet but have tried doing a guildhest twice. By the time I finally hear something about it, I get a "you're doing something else" error after clicking 'join'. When I tried to just cancel what I was doing at the time, I ended up canceling both it and the guildhest invite. :-/ Am I just supposed to stand still for 20 or so minutes until I get the actual invite? And will the same thing happen when I try a group story quest?
