Bumping, its still in the game.
If you die while channel the carpet you will not be able to use any abilities until you channel it again after respawning.
I set custom item hotkeys but they are still shown as Z and X in game (I am using hero-specific hotkeys)
The Items do indeed work on the keys I set but UI is incorrect.
Restarting the game or verifying the files did not fix the issue
