I Did Two Challenge That Were Custom 200 Kills And Head Shots And didnt get the cR
And you also set a time limit for them, wait until the time is finished.
When the time is finished, it may take a while to process. You’ll get your credits eventually.
^this
you should also check waypoint to make sure you redeem your cr when it is up. make sure you didnt duplicate it either or it could eventually result in a ban on reach.

Actually, they’ve changed the system to where if you turn the challenges in, you’ll get them immediately (or almost immediately)! 
Just turned in a small custom challenge an i got the cR a few minutes later, though it was very small. Tho i didn’t get the custom challenge of the week extras with it :(.
