We are playing as a party as two.
The matchmaking found a game, 10 players were ready and then I received a “matchmaking error”.
My friend stopped the search. Then he couldn’t start it again as he received a penalty.
Nothing in the UI indicated that we were doing anything wrong, thus I am writing here. In that scenario, we shouldn’t have received a penalty.
edit:
The problem exists in solo-matchmaking, too. I just received a penalty for failures in the matchmaking process.
