Say for example you have 2 players in a Q for AV, and you invite a 3rd player and Q then also for WSG but not AV.
The action of Q’n for WSG seems to also then include the 3rd player into the AV Q.
You cannot as the 3rd member or any other non-lead drop Q, only the group leader can.
Uninstalled all Addons, made no difference.
I don’t know if this is a real thing or just a display bug, ill test more when I have time.
