unhappy colonists slaughtering livestock? [solved]

[mulholland]

I have (had?!) several tamed turkeys. [a16] Earlier in the game, I noticed that other tamed animals (two, but at different instances) had their 'neck cut', but I had never ordered any colonist to butcher any of them. We also had adequate of food. Now I suddenly witnessed my colonist - Star - butchering one turkey and then heading off to kill another! Why is this happening? He has the traits 'hard worker' 'ugly' and 'neurotic', and is incapable of 'dumb labor' ' intellectual' and 'artistic'. He is a recruited raider. How the heck am I going to keep him away from my livestock? Does he have some sort of 'sociopath' trait that is hidden?
I don't know if it is related, but a psychich drone had just landed.

A couple of seasons later, I suddenly catched Stars going for another killing spree, but luckily managed to stop him before he killed more than one. Last time it coincided with a psychic droid. We all know that messes up moods. This time I could see his was really, really low and angry. So, my question the is: Has anyone seen their colonists doing shit like this when being in a really, really bad mood? My guy slits animals necks!!!! :-O

Now he is at it again, but he's very happy, so why the heck does he keep killing my livestock!!

Lol, I was kinda hoping this was some hidden quirks that my colonists got, but it seems I neglected to check my Colony Manager mod. I had there set the number of animals to a lower number than I had, and set them to butcher the excess... Solved!

Too bad about those traits not suddenly popping up!

Mental Break - Animal Decapitation.
The final straw was - Bonded animal died.

"Man, I loved that turkey. That turkey was my best friend. And then they overcooked it and it was too dry! That's it! That's the last straw! Yer all gonna DIE!"
