The Halo games Halo Spartan Assault one of the achievement is Extra Credits and is ask you to complete 90 specific assault ops for all the missions. I’m at 89 completions for the assault ops but the 90 ops is glitched for me every time I try to complete the assault op it just keeps on going up instead of completing. The op is on the first mission “Warm up that pitching arm” and it asks you to “kill three grunt majors with frag grenades” 0/3 and the completed version should look like this 3/3 but my taskbar just keeps on going up every single time I try to complete the op I am now at 1134/3 completions on the Xbox 360 and Xbox one. Before you ask yes I have checked multiple times I’ve completed every single ops except the one that just keeps on going infinitely. I have contacted Xbox support. I have deleted the game on the xbox 360 and the Xbox one. I have even uninstalled my account and the gamed and redownloaded both of them. I even made new account and file shared all my games with my new account and try to do that op and it completed on that other account. It’s the last achievement I need for that game too. Can someone please help me fix this glitching my taskbar. Gamertag is Foxwithoutsocks.
