So, I was playing Factorio on my laptop, and went AFK without plugging it in. The laptop hibernates before it runs out of power, and this time was no exception. Most of the currently running processes were saved to disk. Factorio, however, was not open when I turned my computer back on.
I should mention that I am using some mods (Namely, the entirety of both the Bob's Mods series and the Angel's Mods series, as well as Clock, Void Chest +, ShinyBobGFX, and Recycling Machines). I don't think these would cause this issue, but it is worth noting.
