Achievement 139% Completion Won't Unlock

So I just got 23000 points on Oni alpha Sites in Halo 3 ODST. Says on the website that I’m at 139% completion for the achievement but it wont unlock. Doesn’t even say it’s in the state of unlocking. What do?

That my friend is a glitch. My advice, wait for 343 to fix it.

I’m guessing this is H3 ODST for Xbox 360 since ODST on the Xbone MCC didn’t come with firefight?

That’s interesting, I haven’t heard of this glitch before. My friend and I beat it about a month ago and he got the achievement (I already had it, so…)

Can you give more info?

He’s talking about campaign score. He was going for par score on the mission Oni Alpha Site in the campaign. That’s extremely odd. I got nothing for ya bud. Sorry.

I’ve still got two Audio Log achievements (#7 and #9) that are stuck on, “Done, Unlocking…” Wish somebody from 343i would acknowledge this issue and let us know they’re working it.

Update: Bravo responded to me on Twitter last night regarding the stuck achievement issue for ODST. Please go favorite this Tweet to show 343i that you’re interested in getting a fix to this issue!
