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.
