sometimes it is most likely faster to break the tamed mode (not aggressive after taming procedure) once by walking far enough away from the animal youre taming. ever tried that?
but, not to nullify the taming points when walking away:
- do not cross a claim border - if you are taming on a claimed land, dont leave that area, if you are taming on an unclaimed land, dont enter any claimed areas.
- do not swim, dont get on a boat/raft
- do not teleport
- do not enter a house or a cave
any of the above may not influence, but many of us believe that the taming points get nullified by those actions (and directly attacking the animal youre taming as you read). fyi, it once made me wait for 30 mins for the second taming attempt.
it would be much easier to tame one from a herd so that you could use others from the herd to get the whole herd aggressive instead of waiting for natural aggro.
