Custom Heli Crash script spawning Helis without smoke/fire

[Daniel Kagarise]

So im using this script found below to spawn in my heli crashes the old school way, everything spwans in correctly ingame except for the fact there is no smoke/fire on the wrecks. Would anyone know how to fix this? No that isnt the entire loot table, shortened it to shorten the post.

private["_position","_veh","_num","_config","_itemType","_itemChance","_weights","_index","_iArray"];

waitUntil{!isNil "BIS_fnc_selectRandom"};
if (isDedicated) then {
_position = [getMarkerPos "center",0,4000,10,0,2000,0] call BIS_fnc_findSafePos;

_randomvehicle = ["UH1Wreck_DZ"] call BIS_fnc_selectRandom;
_vehicleloottype = ["HeliCrash"] call BIS_fnc_selectRandom;

_veh = createVehicle [_randomvehicle,_position, [], 0, "CAN_COLLIDE"];
dayz_serverObjectMonitor set [count dayz_serverObjectMonitor,_veh];
_veh setVariable ["ObjectID",1,true];

dayzFire = [_veh,2,time,false,false];
publicVariable "dayzFire";
if (isServer) then {
nul=dayzFire spawn BIS_Effects_Burn;
};

_num = round(random 5) + 3;

if (_randomvehicle == "UH1Wreck_DZ") then { _num = round(random 3) + 4; };

switch (_vehicleloottype) do {
case "HeliCrash": {
_itemType = [["Skin_Sniper1_DZ","magazine"], ["Skin_Soldier1_DZ", "magazine"], ["DZ_Backpack_EP1","object"]];
_itemChance = [0.01, 0.01, 0.015];
};
};

diag_log("DEBUG: Spawning a " + str (_randomvehicle) + " at " + str(_position) + " with loot type " + str(_vehicleloottype) + " With total loot drops = " + str(_num));

waituntil {!isnil "fnc_buildWeightedArray"};

_weights = [];
_weights =[_itemType,_itemChance] call fnc_buildWeightedArray;
for "_x" from 1 to _num do {
_index = _weights call BIS_fnc_selectRandom;
sleep 1;
if (count _itemType > _index) then {
_iArray = _itemType select _index;
_iArray set [2,_position];
_iArray set [3,5];
_iArray call spawn_loot;
_nearby = _position nearObjects ["WeaponHolder",20];
{
_x setVariable ["permaLoot",true];
} forEach _nearBy;
};
};
};

its a modifed version of the carepackage or wreck drops
