In one of my saved worlds (bry survival sa3), I am unable to interact with passive mobs. I have tamed cats, birds, and wolves that had been set in my home base. I am no longer able to toggle them between sit and stay and they have roamed off (the cats are now red in color). I also have cows, sheep, pigs, chickens, and mooshrooms in pens that I am no longer able to breed. For example, if i am holding seeds to breed the chickens, they will run towards me but I am not able to feed them.
