Start debug console and define this function:

KK_fnc_placeClaymoreAI = {
_this playActionNow "PutDown";
_this selectWeapon "DirectionalMineRemoteMuzzle";
_this fire [

		"DirectionalMineRemoteMuzzle",
		"DirectionalMineRemoteMuzzle",
		"ClaymoreDirectionalMine_Remote_Mag"

];
};

Now walk towards Explosive Specialist and point at him. You see option to look in his backpack. Open it, you will see he has 2 Claymores.

Execute this piece of code:

• spawn {

sleep 1;
cursorTarget call KK_fnc_placeClaymoreAI;
};

You hear beep and Explosive Specialist places 1 Claymore.

Repeat, he places another one
Repeat, no beep, no claymore, he ran out of them. So far so good.

Restart preview

Redefine the function (now with inventory check)

KK_fnc_placeClaymoreAI = {
if ("ClaymoreDirectionalMine_Remote_Mag" in magazines _this) then {

		_this playActionNow "PutDown";
		_this selectWeapon "DirectionalMineRemoteMuzzle";
		_this fire [
			"DirectionalMineRemoteMuzzle",
			"DirectionalMineRemoteMuzzle",
			"ClaymoreDirectionalMine_Remote_Mag"
		];

};
};

Note the change (if condition)

Point at the Explosive specialist and execute:

• spawn {

sleep 1;
cursorTarget call KK_fnc_placeClaymoreAI;
};

He places Claymore. Look in his backpack, no more claymores!!! ??? Execute script again - nope, nothing.

The following all lead to all Claymored disappearing after just 1 run

"ClaymoreDirectionalMine_Remote_Mag" in magazines _this
magazines find "ClaymoreDirectionalMine_Remote_Mag" >= 0
"ClaymoreDirectionalMine_Remote_Mag" in itemsWithMagazines _this
itemsWithMagazines find "ClaymoreDirectionalMine_Remote_Mag" >= 0
{_x == "ClaymoreDirectionalMine_Remote_Mag"} count magazines > 0
etc..

if (true) then {.... however works fine, so this is not the statement, it is the content of it.

As I said very very weird behaviour.
