Probably due to a software bug, a random sample of my sidecar files got corrupted. Luckily not the most biggest of problems out there, but sometimes some files really needed sweat and tears to get where they need to be. My sidecar files get backed up with the raw files but this is where I made my mistake. The raw files don't change but the sidecars you have to treat as volatile assets. Backup your raw files once, twice but backup your sidecars twice as often, and don't delete the old ones.
