GETTING REMOVED FROM GROUPS CONSTANTLY

get invite.. accept invite.. see all the lovely people... TP to person's HO... get REMOVED from group yet in current groups there is sits "Accept/Decline" but i cant accept.. only decline

So of course in ROTA's because i have to decline after already being in the group.. i get replaced.

This happens after getting an invite and accepting.. and clicking the persons swirly thing to go to them. It is removing me from group. Many times.. not the lead person kicking or anything because the 'invite' sits in the Social > Party area as if i never clicked accept in first place
