It's an bug, if you have that challenge on, you have to do it in one go, that's how i get mine. I also notice that if you have the challenge on,don't do any thing, exit the game completely and start again. If you're lucky enough the challenge will still be there and award you with 25 extra challenge credit and say " the previous challenge had expired". now with 50 challenge credit, you only have to get 13 more and the rest will be easy. hope you get prime killer frost, she's awesome.
