Newest update (0.8.4.6) kills on 18+ defeat. The scene happens, then you die. I think it's an unintended effect of the latest patch. Update: I think it was due to a weird Grit bug. It stopped happening at lvl 6 when I got the notification that I could accept more violent encounters. Grit is definitely not able to be seen like older versions, though. Also, a save file glitch caused me to lose all progress and start over at lvl 1 with the default character. Not sure what happened, but that save file defaulted to a blank slate.
