Eternal Mana Absorption. The Black Doubt Hexer's Robe and Demon Form.

Good afternoon, I hope I have correctly understood how to report bugs, if something created wrong - I apologize, the first time I do this.
The bug is related to the item: The Black Doubt
Hexer's Robe and Demon Form skill.
I can't make it intentional, but periodically when exiting the form the mana absorption doesn't stop until you get to the character select screen. Also maybe it is related to the moment of finding the waypoint when in demonic form.
Thank you for your attention, I hope the information was useful.
