there is something else happened, when I joined in the group first time.. it was fine until I did 2 dungeons. after that I couldn’t join across server. the other thing I noticed was when I joined, the game automatically guest me to that server and when 2 of the guest were gone I couldn’t join any more groups and I couldn’t guest since my guest were automatically filled up. I also asked bunch of other people, they said they can’t guest. for some reason they already guest to other server even though they didn’t. some said they blocked from guesting
I have comfirmed that my situation is the same. The people I joined were from the two servers I now appear to be guesting. Very anyoing as the people I play with are on different servers than the ones automatically asigned to now.
