When specifying the from object from ropeCreate as argument of ropeAttachTo, arma 3 comes to an abrupt halt.

Set a F/A-181 (f) and Huron (h) up, put this in init.sqf:

[] spawn {
	ropeCreate [h, [0,0,0], f, f selectionPosition "tailhook", f distance h];

	[h, [0,0,0]] ropeAttachTo (ropes h # 0);
};

Note that h is used as from object in ropeCreate and as argument to ropeAttachTo.
