No skulls on normal?

Games Other Halo

I went to sierra 117 on normal and went into the small corner like it should be, but it didn’t appear at all. Why?

I had a friend who had the same issue and never figured out why. We ended up just playing some co-op so when I picked up the skull he got the achievement. It seems to be some odd bug or something.

Maybe it has something to do with rally points?

Yep. To get the skulls you have to start at the beginning of the mission.
