Bad UX
Hah.
Lost my save file due to bad UX. Was hovering over my save file and when I went to select it I accidently button mashed and pressed the delete and the select button at the same time.
There goes 13 hours.
I was having fun too, playing for the second time to play the DLC (really good btw) after my first playthrough months ago.
I'll try another playthrough at some point, I give it a month at max, but I'll take a break from it for a while, that was pretty demoralizing.
