Just as the title says, Im getting "removed from group" as soon as I accept the invite. I am up to date 1.8.2a

If you run Elvui, TukUI, or other addons which auto accept group invitations disable the addons auto accept group invites / friend requets funciontalities as they cause conflicts with oQueue.

This is the cause of 90% of the occurances of this issue. 

I have same error if i make new premade after invite someone got decline invitation message.
I removed all addon only oqueue in addon directory and delete all content in WTF directory, and this problem already still up.

oqueue: v1.8.2a
wow: 5.4.7(17956) x64
