Weekly challenges 12/28

So… I did this:
Imgur

screencap of the waypoint record:
Midnight, solo, legendary, Cloud, Catch, Tough Luck, Cowbell, Birthday, IWHBYD

expecting to get:
-Still alone in the dark
(midnight, solo, legendary)
-Grenade happy
(Campaign, >Heroic, Cloud, Catch, Tough Luck)

And because I didn’t go back and re-read the requirements for skullduggery, I had the three extras. I got Skullduggery, and that’s it.

At the very least I ought to have gotten Still alone In the Dark. What gives?

The challenges are VERY specific. You can only activate the skulls required in the challenge description. Any extras and it negates the challenge, which is a bit stupid really. Its happened to me before on Halo 4 and Reach challenges.

Unfortunate. I just came back to confirm. Did Dawn and took out the extras, lo and behold, success. I suppose I’ll catch it anyway (may as well hit it up on my way to the legendary ending)
