Now here is where the fun starts.
Sometimes you will get "Session lost" after about 5 minutes of joining a server. But if you keep joining the same server after about 3 times or joining leaving joining etc... you will no longer get kicked from ANY server.
I'm making this private as im unsure if anyone has figured this out yet.
Some .pbo's work 100% some will kick you more often.
structres_Buildingswip.pbo kicks alot more often then stuctures_walls.pbo for some reason.
