Essence Drain Bug

I am playing as the Witch, and I just ran into a problem with Essence Drain getting removed from my skill bar. I recut the skill using an uncut gem 5 different times. Essence Drain will then work for me until I quit the game or use a waypoint to teleport. It will then get removed from my skill bar and I can't drag it back or assign it to a hotkey. When I click on the arrow to show the information for the skill, it shows up as a different skill or it will say this information is currently unavailable.

I uninstalled the game and reinstalled it. Recut the skill and it has been working fine since.

just had this issue as well. i cut a new essence drain gem. if i remove it the skill breaks again and can't put it on skill bar or look at the skill info. not sure what to do build is broken at level 65 and unplayable
