Quote from Pontifex Maximus
With all this new information comes the question:
Will there be an easier way to move animals in the future? I hope so. That's a question for a different topic though.
It's a shame that you have to go through such a crazy endeavor to get animals to respawn. It seems extremely unlikely that my starting area will ever get animals unless I do something to surrounding areas.
How are you moving animals? I find by minecart is easy as hell, you can move them so far away.
