Some of our pigs seem to be dying for no apparent reason. Pretty much every 2-3 days I find one adult pig dead.
At first I thought they were getting sick and die over night (8-10 hours max seemed a bit too soon for sickness to kill them, but whatever, Salem can be harsh).
One of them had 5 longevity, so I thought maybe it was it's time. We killed all the other animals with same-ish longevity, so there's no way to check.
The one I found dead recently died soon after giving birth, so I thought maybe they can't procreate too often without their health being affected or maybe it is just a random thing that can happen.
I also had "not enough food" theory, but there is always some food and adult animals are locked up with food throughs, so it is unlikely they have any trouble reaching it.
But the last one I found just few minutes ago and I am 100% certain it was not sick, because I just checked on all the animals not so long ago. It had 30+ longevity, food through under her nose and no signs of sickness.
We also keep temperament of all animals close to 0.
What could be the case?
Am I missing something or are there any sudden death bugs still present?
Here are stats of two most recent ones if that helps:
