VSQuest/VSVillage Kills not counting toward progress

I'm using VSVillage and attempting to do the Mayor quest where he tasks you with providing food, jobs, houses, and killing drifters. I can complete all of the other items, but no matter how many drifters I kill, or seemingly of what type, I'm still at 0/30 kills
Unfortunately, as far as I can tell, there's no error or warning in the logs regarding it.
