H2A coop Legendary progress not registered

So I just played 3h30 hours (including Gravemind and its retarded start) and hasn’t hosted only to see that none of my progress has been registered. This has been notified plenty of time you can see by googling this problem. How is it not fixed? Legendary Halo 2 is one the hardest game ever and your progress doesn’t save what the actual -Yoink-. I don’t even know if it’s worth submitting a tickets. It never lead anywhere and it’s not like if it was an unknown bug. Please fix this. I can’t believe I have to redo Gravemind the two previous missions and this BS game design again. I am the incarnation of salt right now.

according to you’re service record it say that you have gravemind done on legendary EDIT oh its co-op nvm

I don’t have a fix, but I do have a way to make the Gravemind grind easier. Follow the Halo Completionist guide on the Monopolised achievement and use that to quickly finish Gravemind.
