Please correct that wolves do not attack the player when compare with tag Angry:1. Of being seen, they immediately become very peaceful and it prevents me to create maps, but PigZombie they work, and with no wolves

Initially, the problem was a bug call in the middle of last year (the first Snap 1.8) is fixed a, but now wolf call of the status of the "angry" does not work in principle, because the wolf immediately returns to "neutral" status, as it has no targets available.

Please read https://bugs.mojang.com/browse/MC-33558

Another thing is if the wolf did not attack if there is no nearby targets or you can choose to target for attack, but the tag is simply never works and senseless
