Wolf summoned by pounce disappear

Since the start of act 3 my wolf summoned by pounce sometimes disappear instantly without even taking damage. Sometimes they'll last a few seconds, but its not possible to maintain them at all. Didn't have this problem before act 3.

Is it because you are weapon swapping? I notice that if Pounce is only active on set 1, and I summon wolves, then swapping to set 1 will cause the wolves to disappear. I am pretty sure this is a bug

The wolves do not appear at all after Act III onwards, using pounce.

Did the same thing for me and I found out that Freezing mark socket in pounce, predator’s mark will be replaced.
