Campaign challenges

[probably my BR]

A couple weeks ago i tried getting one of the campaign challenges completed. It was the challenge were you gotta beat any mission heroic or higher with tilt,storm and tough luck skulls. I played it solo on legendary and it took me a long time to beat and after beating the mission i didn't get the challenge. I doubled checked everything and nothing was wrong. So i tried again another day different mission same skulls on legendary solo. Once again it took me forever and i didn't get the challenge. I went back and read the challenge statement a billion times and nothing was wrong. WTF am i doing wrong.

well...first make sure the 4 skulls are on, which are usually tilt, mythic, tough luck, and thunderstorm.

 

Then, and this is important, you have to do a mission from Rally point alpha, or the beginning of the level, doing it from any other rally point will not count toward the challenge.

quadruple checked the skulls and completed two missions from the very start. This game is broke.

Im tryin to do this weeks challenge with all these 4 skulls on, on the composer map! But I can not seem to put a dent in the elites at all, I charged the plasma pistol hit with that then 2 plasma nades an it still didn't take his armour down? Now at this rate with the amount of ammo its takin to take 1 down there not gonna be enough to do the full landin bay!! Any help would be most appreciated:-/!

 

Oh and to ur post ur xbox didnt disconnect from xbox live at any point did it? I had it before were it said I hadnt finished the game cuz of it, so maybe its that!

Challenges in campaign with skulls on are hard. I, honestly think I SUCK at them.
