[MH2] Dauthi Voidwalker issue

Hi, guys! Sorry if it's not the appropriate section for this but I would like to signal an issue regarding Dauthi Voidwalker's effect.

When a permanent leaves the battlefield, Dauthi exiles it but doesn't place a void counter and thus can not cast it at a later time. It happens only with permanents going from the field to the grave. Thanks and congrats to everybody for the hard work!
Cheers!
