create dayz_server/init/cleaner.sqf:
while {true} do {
{
if (count units _x==0) then {
deleteGroup _x;
//diag_log ("CUSTOM: GROUP CLEANUP");
};
} forEach allGroups;
sleep 300; // run every 5min
}
add this line to the bottom of dayz_server/init/server_functions.sqf:
[] execVM "\z\addons\dayz_server\init\cleaner.sqf";
What this does is clean groups every 5 mins so seagulls should last no longer than that. Can confirm it works on our server.
