Render out of sync audio issue

Just wanted to say that I am also experiencing audio being slightly out of sync after rendering. This is using the standard YouTube present with no changes to it.
However it doesn't happen all the time and the solution is to just re-render your project. Which is usually OK, except for the time lost however under deadline it's a critical roadblock.
This morning I did a 3 minute video and the audio was off in QT playback. I deleted the render job, reset it, re-rendered it and this time it was perfect. I did not restart the system.
Is this on Blackmagic's radar?
