Halo 3 and Halo ODST times tracking together

Game: Halo 3
Issue: Times being tracked incorrectly

Hi there,

I’ve added up my times for ODST and I’m seeing 2:17~ for my total time across all my best times - which should grant me the under 3 hours achievement, right? Except it hasn’t, from what I can see on my Service History my legendary time is over 5 hours leading me to believe the total times from Halo 3 and ODST are being added onto eachother and preventing me from getting the achievement.

Is there any chance we can see these timings separated - I’ve got another friend with what seems to be the exact same issue, when he checked his Halo 3 total time racked up over 8 hours.

They do track together, and it would be nice if they fully separated the two. I just completed this achievement, my run time on halo 3 legendary is like 6 hours (haven’t gone back to speed run)

On my service record it says fastest clear time (legendary) 9:12.

so that didn’t effect the achievement for me.

Did you do all 8 parts of the Mombasa streets missions?
