Teams that prefer listen servers will no longer be matched with teams that prefer dedicated servers

Official dedicated servers are now preferred when searching for team matches

Players who crash or have failed to load are no longer banned if they have been kicked

Update Russian subtitles

Fixed not being able to interlink teams in team-on-team mode

Fixed not being able to properly migrate team lobby after team leader would leave the lobby

Fixed not being able to invite friends if player was not team leader in a team-on-team game
