Holy moly, I've just realized a failure. I put in my card to import the RAW images to Lightroom and was a little confused at first because the file numbering started over (9999+). I imported the new 000X files, but forgot to look at the tail end of the 999X files, so I lost the shots I took on the 3rd.
Luckily, the subject matter for that day is a large and immobile county feature, so I've decided to allow myself to go back and re-shoot it.
Technically, for Single In Challenge purposes, it's a miss, but spiritually I'm going to be at peace with it.
Please learn from my mistakes.
