Recently, something strange has happened to me while trying to use the Mask of the Night's Lord.

I had transferred it from another character through the Global Bank (it was working before this), and once I got it on the character I wanted, I went ahead and killed a few mobs for the sake of having forms.
To my surprise, once I changed forms and tried to toggle the mask on, nothing happened.
When I tried to use the mask again, the menu was no longer appearing.
I've tried relogging, and putting the mask back on Global Bank and then taking it out again (this causes the menu to appear once using the mask, but the same happens where trying to toggle the mask on doesn't work, and the menu doesn't appear), but nothing seems to work.
