A while back, I created a post about animals no longer displaying their bored animations. [It's been many years since I played the vanilla version, so I can't remember if that one actually worked fine]

And I noticed that there was another post about this:

After copying and pasting the code several times, I noticed that the , of the animals is breaking the code. If it's there animals don't play their bored animations. I used the dead replacement unit, to make sure that the hunting is still possible, but it kind of damages the gameplay mechanic a bit.
