Chase Behaviour Pack broken ?!

[André Bouchoms]

According to the latest update, some dinosaurs can hunt together (see list below). However, according to numerous tests, this doesn't work. How do you select several carnivores and get them to hunt together?
Can you explain...
Thanks in advance.

Chase Behaviour Pack
● Selected carnivorous dinosaurs will now chase alongside a same species hunter as they go after their prey

Applies to:
● Yutyrannus
● Australovenator
● Concavenator
● Cryolophosaurus
● Herrerasaurus
● Monolophosaurus
● Utahraptor
● Troodon

it just means that, if one of this species startet to hunt something, one or more others of the same species also start running / chasing the same target.
But there are no extra animations for 2 or more dinosaurs kill 1 target.
They just running together, while still 1 will start the killing animation.
