I know this is an old topic to bring up...but...

So I finished Halo CE - 4 on legendary and even checked on here to see if waypoint was correct and it says all missions were played on legendary but i still havent gotten helioskrill and this will be the 2nd day since ive finished Halo 4. Has anyone ever had to wait more than 2 days? Or is there something im missing that needs to be done?
