The only simple solution I see is to go back to normal invitation rather than auto joined game.
Problem of missed invitations seems less serious to me than deadbeating player in many auto tournament. Got for example 2 deadbeats in the same group, in which we had like 7 games or so. Also got deabeat in polymorphic game. And I am not in but I have seen deadbeat in assassin tournament / that really ruin your game in assassin when your target changes.
Smthg need to be done to adress this problem.
