Good luck then. There's no way until next patch which will have a loophole.
Thanks anyways Bro but you want to help? What I've done here in one out of my two theories is set the party limit to 2 then add my second once the seconds in I set the party limit to 1 start the game join someone then the map disappears but I am still able to use the functions but when I try to change map nothing is happening.
My next theory I was going to try the spam method again but instead of going into a game I was going to lag myself as I'm searching with my second quickly suspend before it puts me into a game and then come back about a minute later why the custom game loaded is still popping up then invite people?
