Hello. I am encountering a bug for Halo Sparan Assault for Xbox 360 where I am unable to obtain the extra credit achievement. I have 89/90 Assault Ops completed and the last assault op (warm up that pitching arm in mission one) shows 103/3 instead of complete. I saw that some xbox one users had similar bugs, but I have not seen any reports on xbox 360. If anyone can offer some help or is in a similar boat, please let me know.
I have the same problem on the 360. I’ve been posting about it in the similar thread for the XB1 but I’m sure it’s the same problem on both platforms since the stats carry over, so once one is fixed, the other should be fixed at the same time.
I call this Glitch 2 in the thread Kyle mentions.
One difference between HawaiianShorts and Kyle is that HawaiianShorts never played the game on Xbox One, according to his TA profile. He did play Win 8 back in August.
I had assumed that Kyle’s incorrect counter occurred on X1 and then the bad stats just transferred to 360. Now I’m not sure whether his bug originally occurred on X1 or 360.
But now we have an example of the error probably occurring solely on 360. There’s a chance the problem originated on Win 8, but I’m guessing not since there doesn’t seem to be any reports of this error before the X1 version came out. (On the other hand, that could just be because Extra Credit only requires 75/90 on Win 8 and WP8.)
I have changed the name of the original thread to mention 360 and edited the OP. I feel that consolidating reports there would be beneficial to 343i as they work to fix this.
Will pass this along to the team for investigation, hawaiianshorts.
Thank you for consolidating and updating the other thread, MathGuy42. Appreciate the organization; it helps tremendously for tracking purposes. 
bs angel, you are quite welcome. I am just trying to do what little I can to help on the consumer end.
Do you have any updates on a fix for Extra Credit on One and 360? I am nearing 100K GS and would love to have a Halo game put me over the line. For the sake of others, I’m also concerned about the glitched Halo 4 DLC achievements. Thanks.

Will post updates in relevant threads as we have them.
As far as this one goes, for those of you stuck, could you try completing a Weekly Challenge and see if that unlocks the achievement, please?

Thanks for the response. I hope you can shake more details out of whomever is in charge of the fix.
You are probably addressing 360 users, but just in case, I just completed another Weekly Challenge on Xbox One. Extra Credit did not unlock and the achievement progress is still at 0%. I am experiencing Glitch 1 since I had previously completed the game on both Windows 8 and WP8.

The Xbox One version is going to be a slightly different issue than the Xbox 360 one so for this thread, I do need 360-specific details. Thanks for checking.
I don’t know if this will assist or not, but I am also experiencing Glitch 2 for the Xbox 360.
I do not own, nor have I ever played, SA on any system other than the 360.
On Mission A-1, I noticed the other day I had 8/3 Grunt kills, and it is not registered as complete. When I played A-1 again, I got 4 more qualifying kills, and now the counter on the Assault Op says 12/3.
I hope this information is useful.
Thanks for the info, IdioticYsgard. Will pass it along to the team.
I am experiencing the 360 glitch also. A-1 Op 1 my counter is at 510/3 which makes me think its counting kills for every mission. The counter for Op 2 is at 166/20, so I’m stuck at 88 of 90. Tried completing weekly Ops no change. I didn’t have the problem right away either not 'til about E mission. Thanx.

Like SerpentsDragons, I am stuck at 88/90, except A-1 Op#1 and Op#3 are glitched, Op#2 is fine. I also didn’t have the problem right away until around the time I was completing the Running Low and/or Dark Clouds challenges on Xbox One. So it seemed like something in Operation E may have triggered it.
I tried completing a weekly challenge last night on the 360. It didn’t unlock. Hope this helps!
