I got a problem with Oqueue.
Where I find a group and get an invite. As soon as I accept it I then leave group automatically and withour reason.

any idea why this is happening?

If you play with ElvUI, you must disable auto-accept invitations in general options.

I had the same problem.

Yes I'm using elvui and yes I had auto-accept invitations enabled.
thank you for the help, seems to have solved my problem to.
