I friggin love Halo. Its all about the nostalgia and gameplay for me. What baffles me is the lengths this game used to go through to make challenges rewarding for people, (i.e. recon and hyabusa armor, scarab gun, skulls, and just general easter eggs) has now resorted to the challenge structure seen in the call of dutys and fortnites of today, AND released them buggy as hell. I have done at least 30 co-op missions and killed thousands of infantry to go back to the home page and see the glory of a completely filled progress bar. This is where I dont understand why we dont have the ability to claim the credits. In the wonderfully buggy automated claiment system that activates at the end of matches we get screwed on campaign. Exspecially in playlist. If we arent going to be shown the same post match/mission screen that shows the same progress bar animation that the multiplayer does then where is the confusion in fixing this bug. So there you have it 343 two possible fixes for a reward system that is really fun if dependable. And for the love of the forerunners please PLEASE give some sort of retroactive credit bundle to the players that have been active in these seasons. Its really becoming an insane anxiety driven grind at this point and i just want all the things you tease us with.
Issues with challenges are known at the moment OP, but please do make sure and file a bug report about this on the Halo Support site: https://aka.ms/HaloSupport
