Question/bug on legendary campaign?

SO im up to the 6th mission on legendary, however the game is saying I did not get credit for completing the 4th mission “infinity” on legendary, I also didnt get the commendation or achievment for that level, but I did beat it…

On waypoint here and in game it says ive beaten that level on legendary. Anybody else have this issue? And if I have to go back and do it again do I have to do the whole mission or can I start from rallypoint 3 to get the credit?

Help would be greatly appreciated! Thanks in advance

I dunno man, but I’ve had similar experiences. I haven’t checked today, but earlier in the week me and a friend beat Spartan Ops Episode 2 on Legendary and Waypoint doesn’t show me as having completed the final chapter, despite the game stating I have.

its most likely that the server is having issues when you achieve it so it doesnt register. I just did the missions again.

Sigh… I really didn’t like that mission minus the great scenery…

I would play the mission from Rally Point 3 and make sure you finish watching the end of the level cutscene, if it still does not appear I hate to say but you will have to do it again. Sorry Mate.

Thanks for the advice, i’ll just play through the rest of the campaign then do tat mission last so I get the armor/visor
