So I was playing Reach last night, and I just finished two custom challenges for multiplayer that would gain me about 10,000 cR combined. I claimed them on here and all that stuff, and went to bed taking note how I have 886,000 cR saved up (saving for inclement), so I knew tomorrow when I would get on it would be close to 900 K. Get on this morning, and I still have the 886,000 but on here it says completed and in first place. So am I missing something or does it only go towards your rank progression and not cR able to spend?
If you already hit the credit cap before you completed the challenges then that might explain it.
I’ve had the same problem so I just gave up doing any
This is the second time I’ve heard of custom challenges. How do I set up my own custom challenges?
might as well not bother since 50% of the time they don’t even work. in the past few days ive been in games when i’ve got 175 medals while i was working towards my 1000 medals challenge, and they didn’t even count at all towards the custom challenge. I’ve also lost about 100,000 credits in the past couple of days because of not receiving my challenges even after the time expired + 48hours. please fix custom challenges so people are actually motivated to do them rather than expect to not receive credits and lose interest.

I don’t play this game enough to have ever hit the cap
