search the files for spawning zombies .. createagent is the code. But if you never changed those files the zombies themselves are not going to be on wrong side, maybe the players are.
Put this code into the bottom of your init.sqf
if (!isserver) then
{
[] spawn {
while {true} do {
hintsilent format["You are on side %1", side player];
sleep 5;
};
};
};
that should update your hint box every 5 seconds with the players side which should always be WEST unless he is a bandit in which case it should be ENEMY. You will be able to see if and when the players side changes.
As for the spawning dead .. yup, seen that before too .. will take a bit until I remember what the issue is. Are they maybe getting killed by infistar or the overwatch anti-hack because of ESS ? Some type of teleport restriction ..
What does the log say when they spawn in? Dont see anything in the server log, check the client log.
