Last night my friend invited me to a group. I accepted and traveled to the dungeon. When I got there I wasn't in the group so I left and when he tried to invite me again it said I was in a group. I tried to invite him and he gets a failed to join group message. I have tried inviting random people, friends no one can group with me. I can't even search for a group. I made a new character and he can join groups and such no prob so it's just my main character. I have tried everything to fix it. Hard resetting my Xbox, resetting my Internet, closing the game. I was even logged out for like 8 hours while I slept. I still can not group at all on my main character.
