Audio Logs are account unlocks?

so ive had the horrible glitched save bug and have had to restart the game a few times. today during a replay of the beginning mission i noticed it wouldnt let me recollect any audio logs i already collected in prior runs of the first level… is it possible audio logs are actually an unlock attached to your gamertag this whole time meaning you dont have to get everything in one run to 100% complete the game? when i went into tremonous (spelling?) every unlock i had in that area other then the locker and the spartan core had already said i found them as well. just wondering if anyone else had noticed this and/or it was announced and im slow and oblivious lol

I found this too. I didn’t get the achievements for collecting the first skull, audio log for the UNSC, and audio log for the Banished during the first mission, so before the mission finished, I restarted it. Upon restarting it, I found each were gone/off. The case was the same when starting a new save, just to see how it was.

I collected maybe halfish the collectibles in most levels my legendary run. Im doing my easy collectible runtheough and everything except spartan cores seem to be already unlocked. So it does sometimes make following the guide annoying cuz ill be missing1 or 2, and like an idiot go through watching all 8 kr 9 for the 1 i need forgeting time stamps exist in the guide xD
