So I've noticed that a lot of the animal root templates have no sight at all. I don't think it's a stats issue because I can assign them stats entries that do for sure have sight and no vision cone comes up.
None of the cows and most of the dogs are the ones I can think of right now.
This is kind of annoying since I had a cool script where my farmers went around feeding the animals, but they can't see the food so they won't eat it......
