Immediate Disconnection When Shapeshifting

Hello,

I am experiencing a bug where everytime i try to shapeshift in or out of demon form as an infernalist the game DCs.

I tried taking off my support gems from the skill, I tried unlearning and relearning the skill, yet nothing seems to solve this... I even got dced when I clicked to learn the skill again, beyond using it.

Thanks. This is a boring crash hehe
