Is the mod not meant to work in any town or why is the mod completely off in them? The mod works perfectly fine literally anywhere else except cities and towns, where the NPCs obey the normal damage pattern stuff.
Its a lot better than CERR (i think it was called) in my opinion, but the only flaw to me is that the headshot animations are a bit goofy and keep the character standing for too long to be realistic, and should fall down faster. Maybe add some little twitching in the aftermath of one as well !
I installed the regular version of recent and Armadillo has law, and strangely an infinite flow of it from outside the town, and tumbleweed with the same latter issue.
