Hi, actually i just need some help. Since someone leave my first instance today, something is lagging. Nobody can invite me in group, i cant invite people, i cant tag in instance or raid... It just tell me that im in a group but im alone so i cant leave the "group"..

When i try to invite someone in my group, it tell me "This players is not in your instance" and when poeple try to invit me, it say "This player tried to invit you but your already in a group".

So i just dont have any idea what to do for fix this bug if someone could help me.. Sorry for my english btw
