Werewolf Feral Claws bound to left click stops working - V1.3.0.8

I’m playing a werewolf with Feral Claws bound to left click. I play by holding left click constantly and mousing over enemies to attack them.

Sometimes my character stops attacking and stands still doing nothing while I continue to hold left click on an enemy right next to me, leading to my death because my only sustain is leech. I notice it happens often after getting stunned or interrupted, but not always. Releasing left click and then reclicking does not solve the issue; using Evade does.

Thank you!
