Had this problem the other day. Then was fixed. Just ran into it again last match.
THE FIX: Set up a new class and DO NOT use a clan tag or kill counter.
Same here, purple hex camo not progressing on the swordfish and mx9 so far. Xbox one
You're not the only one. I'm having the same issue. I play on Xbox as well.
Same issue on Maddox and Xbox One.
Also the Roller Rink camp for the Hellion not registering direct hit kills. Even went from 6/10 one day to 3/10 the next day.
I figured a fix for xbox to get purple hex camo (for swordfish but should work across all guns). If your gun is prestiged...DONT click CLAN TAG ON. DO NOT.
Create a new class, equip everything BUT CLAN TAG
Same here it's purple hex for all weapons I'm working on wont give me credit towards the 50. Which really messes up the DM grind. Glad more people have this bug, bc it will lead to a faster fix. As opposed to only a few people having the issue they might not care. Hopefully it's fixed by Tuesday and we are all compensated some how for this
