One of my colonists killed another one of my colonists in a social fight. They are not flagged as guilty after that. If that does not flag as guilty, but punching a cow does, I am confused.

My guess is that social fights inhibit the guilty flag.
Both DLCs, no mods used.
Thanks for the bug report. I've gotten this down for internal review. Certainly an oversight!
