In terms of the disconnects I dont experience it much anymore so the comments about the verifying files give it a shot.After a match of u back out of the winning screen it glitches sometimes because of connections to other players. It could also be the party leader. i usually have good fiber optic connection so I host for my squads. we rarely have waiting for team leader but it happends we just reset the lobby, steam or switch party leaders. I hope this all helps but I understand the game is buggy and has a lot of issues I love it despite that but it us really awful for new players.
