Thanks, I disabled my auto accepting invite addon. I wasn't aware it could cause an issue.
Issue upon receiving group invites.
Occasionally upon receiving group invites as soon as I join the group it removes me from the group.
Within the span of 1 second I get this in my chat window.
xyz is now a battletag friend.
xyz has invited you to join a group.
you have joined a group.
you have been removed from the group.
I've had it happen multiple times today and it occurs almost simultaneously with joining.
