The wolves and raptor leap just after me, which I’m assuming is the intended behavior of the node. The Primal Sabertooth just kind of teleports elsewhere and runs to me (because it, at that point, is outside its “leash” range I’m guessing).
I remember such a bug from the multiplayer beta. Just in case you are looking for a quick solution, then you can try to put a point into Heavy Paws in the Sabertooth skill tree. It deactivates the Sabertooth’s own leap ability and made the problem go away for me.
