Need some help with the strategic map fast travel system

[Atlas1205 14]

So I managed to get it to work with pre-defined "missions" as destinations.

_destinations = SAFEHOUSE_LOCATION_ARRAY;

_parentDisplay 	= [] call bis_fnc_displayMission;
_mapCenter 	= (getpos player);
_ORBAT 		= [];
_markers 	= [];
_images 	= [];
_overcast 	= overcast;
_isNight 	= !((dayTime > 6) && (dayTime < 20));
_scale		= 1;
_simul		= true;

[
findDisplay 46,
_mapCenter,
_destinations,
_ORBAT,
_markers,
_images,
_overcast,
_isNight,
_scale,
_simul
] call Bis_fnc_strategicMapOpen;

and the SAFEHOUSE_LOCATION_ARRAY is such:

SAFEHOUSE_LOCATION_ARRAY = [
	[getpos sh_1,player setpos (_this select 0),"Safehouse 1","","","",1,[]],
	[getpos sh_2,player setpos (_this select 0),"Safehouse 2","","","",1,[]]
];
SAFEHOUSE_LOCATION_ARRAY;
publicVariable "SAFEHOUSE_LOCATION_ARRAY";

The two spots work correctly as i could Addaction to any object and open up the strategic map for fast travel to these two locations. However, if i want to add another location by using Pushbackunique, after the game has started, something ugly happens:

SAFEHOUSE_LOCATION_ARRAY pushBackUnique [

	[getpos sh_3,player setpos (_this select 0),"Safehouse 3","","","",1,[]]
];
SAFEHOUSE_LOCATION_ARRAY;
publicVariable "SAFEHOUSE_LOCATION_ARRAY";

 

As you can see, the 3rd location refuses to show up and a script error pops up. So I looked at the line 444 part of that script:

		_map drawIcon [
			_texture,
			[1,1,1,_alpha],
			_pos,
			_size,
			_size,
			_dir,
			if (BIS_fnc_strategicMapOpen_showIconText) then {" " + _title} else {""},
			2,
			0.08,
			"PuristaBold"
		];
	} foreach BIS_fnc_strategicMapOpen_missions;

The _texture has something to do with ORBAT, maybe. the color, alpha and pos should already haven been defined in the first script. I have no idea why it doesn't work.

Can anyone help me please?
