So, I 'like' to butcher the raiders that die in an attack and sell their meat.
However, when my colonists are in the vicinity of my trading beacon and far away from the normal food stock with my meals, they decide to eat human meat instead of going the extra distance to the simple meals.
This is not really a bug, but I don't think it's working as intended either. Normal colonists should not consider eating (raw) human meat when there are other options anywhere on the map. So they should not include human meat in their localized search, only when they do a global search for food.
Fixed now thanks.
