Didn't get Dedicated to Crimson Achievement?

So I did all the chapters for the first five episodes of Spartan Ops, didn’t get that achievement. What in the blue hell is going on? Do I have to do the 5th episode on Legendary because I did the other 4 in Legendary. I know it says any difficulty but I figure if you start on the Highest difficulty then you have to do them all.

If you mean crimson alone its 1 episode solo Legendary.

Do chapter 1 episode 1 really quick and it will pop.

Yep, same thing has happened to me. Completed them all (except 2 chapters, did them on Normal) on either Heroic or above. I’ve got no idea whats going on but I want my cheevo!

Is it possible they have to all be done on solo?

Yea i did not either i had to play one more you need them all on heroic.
