Okay… If anyone is interested. I figured out that one of my clips was corrupt, so the corresponding V1,A1-4 files had to be removed from the MediaFiles directory. Had to use process of elimination method to find the corrupted file and after sifting through about 1,600 total files, I finally found the culprit.
Not sure what could have caused this, and not sure if that file can be salvaged, but locating it seems to have done wonders to fix the system crash issue.
Still working on the other problems, like the offline A1 tracks. It’s a mystery.
