This "lobby backfill bug" absolutely does not exist.

Two lobbies. Both in which a victim left and was replaced in under 20 seconds. Both lobbies eventually closed due to no family members joining.

This supposed bug is pure cope. There aren't enough family players. And if family is so fair and fun like victim mains claim, there would be more family players.

And if this supposed bug that prevents family from joining lobbies does exist, why are family queues near instant?
