Итак, опишу свою проблему:
После обновления до патча 1.0.1.5 (3986) в версус не могут приконнектится больше 4 игроков. Если коннектится пятый, то его выкидывает с сообщением сервер полон, а в консоле пишет #Validation_Reject_Server_Full.
Из того что сделал:
Установил плагин L4D Downtown. Не помогло
Запускал сервер с коммандой +exec server.cfg. Не помогло
Правил конфиг. Прописывал mp_gamemode "versus" и sv_gametypes "versus". Закомментировал z_difficulty "hard". Не помогло.
