It's running again but it still has a peculiar issue that has to do with the supplemental log option.
If I add a supplemental log entry, it moves (or rather, buries) the mission entry all the way to the beginning of my log to replace the very first entry. Obviously this takes the log entry out of the chronological order the mission was accomplished in.
I imagine if you add supplemental logs to enough entries the entire listing would look like a chaotic mess. I made this supplemental log entry through the Captain's Database on the forum, and I'm not sure if the problematic result is the same when making a supplemental log entry from within the game. I'm understandably hesitant to try at the risk of scrambling my log even further, but perhaps someone who has already attempted this from within the game could chime in with their results.
