Just checked the active SQF scripts on server and saw the Wreck_Heli_Attack_01.sqf script in the list.

It is called by the init EH of Land_Wreck_Heli_Attack_01_F and it shouldn't run on the server (or HC) as it is only visual.

Please put a "If (!hasinterface) exitwith {}" in the script (or in the config itself).
