Why Do Exports Hate Me?

Once I fixed that 'noise' problem, I came across another. Once exported, there were times when a loud crack in the audio could be heard. The frustrating thing was, everything it exported, it moved position so I couldn't hone in on the problem. I tried opening the file in CS6, exporting different codecs, edit the audio in Audition but nothing seemed to work. I then came up with the idea of nesting the audio so it was on one track. This way I could export the audio alone and sync it back with the video. I exported the audio about 30 times. This allowed me to remove the audio glitch and replace it with audio that was clean.
