I bought Halo Spartan Assault a while ago for the Xbox 360 and Xbox one. I went after all the achievements for Halo Spartan Assault. I have a bug in one of the Achievements. The achievement is called Extra Credit. I have completed all the campaign mission specific Assault Ops but one of the Assault Ops but one of the Assault Op will not complete it just keeps on going up after I finish the amount it asked for. The Assault Op ask you to complete the op by killing 3 grunts Minors with one frag Grenade on the first mission A-1 and the total amount is three times to complete the taskbar. My progress bar just keeps on going up I’m at 1106 / 3. Every time I do the mission and do the challenge it just keeps on going up without completing. It’s my last specific assault Ops. I have completed all of the specific assault Ops I have checked multiple times they are all completed except the one that keeps on going up.
Which platform did you complete these Ops on? The reason I’m asking is because there are many bugs related to the cross-plat tracking of these Assault Ops. For instance, if you completed this specific Op on the 360 but then completed all of them on the Xbox One, the game may think you’ve already completed the Op.
I try to complete it on the 360 first in 2014 and later on Xbox one edition. I’ve tried every single way to troubleshoot it nothing works.
