BanPods

Yo, so I recently got into arma cause of my friend and we wanted to play liberations, the problem came when he started a LAN server through hamachi I could join but couldn't choose any roles or anything and when he started the server I wouldn't get into the game. Then we tried a way where I hosted which works but it's very laggy a lot of desync happens and I don't see half the shit he spawns with zeus, is there any way to fix this issue where his hosting isn't fucked up for me?
