*Animals should shreak, growl, or otherwise signal that they will consider aggroing you before they do, giving you chance to back off/retreat
*If you run away long enough, the animal will drop aggro. It's asinine that you can essentially run a mile and the animal will chase you keeping the same pace until you finally run out of stamina/grassland terrain and then just ruins your day before resuming random pathing. Most animals would avoid unnecessary energy expenditure.
