There are many servers of KotH (Sa-Matra's one). Almost every time I get crash at CA/US serves on loading screen after receiving data. It crashes randomly, one day it can be alright and you join (then crash while playing lol), next time you get crash on loading. If crash happens on loading it will repeat every time untill server restart. Same with EU servers and others. The only two working for me where crashes are unlikely are FR#1 and WS.ARMA.SU UK#1. But today both of them started to crash aswell. WS on loading after receiving data. And FR#1 when I just got in game ran few meters and game stopped working. Another problem is that Receiving data stops close to the end and I get kicked for lobby idle(RU and CA/US servers only) because it simply doesn't load. Also if you pass loading and get in game, soon after that MISSION FAILED screen appears and there are two options : I'm ready & disconnect (everywhere except fr and uk servers).
Other gamemodes working well.
