no what you did there broke the crate spawn.
Basically this is what it means...
//Weapons, tools, items, pistols, backpacks
[_crate,10,10,[100,crate_items_president],10,10] call dynamic_crate;
if its just a number, it randomly takes from the "weapons array" here: https://github.com/f3cuk/WICKED-AI/blob/master/WAI/config.sqf#L100
or like you did, you specified 100 items of the array presidents crate here https://github.com/f3cuk/WICKED-AI/blob/master/WAI/config.sqf#L269
what ever you do, keep the array the way it is, if you move stuff around like this
[_crate,[100,crate_items_president],10,10,10,10] call dynamic_crate
^^^^ it wont work
