I'm not sure if it's emulinker-k specific or some sort of emulinker config setting, but I think on the new servers whenever p2 or p3 or p4 drops from the game, the whole lobby freezes/crashes/etc. Instead of letting the remaining players in the lobby continue to play.
Maybe it's emulinker-k? I tested myself and had issue on gcore and tnahosting emulinker-k servers, and old chicago server and wils NY server no issue.
