I have looked and not found a response to this issue. This is only an issue with the Zero F's, not with the Sadist talent. I was able to do that just fine. I bought a Zero F's at the vendor and tried, but only got the grayed out "donate" button. I tried using my old (don't remember if it was looted or awarded), and still no good.
I logged out and came back in.
I closed out and came back in.
I shut down, restarted and came back in.
What can I do to fix this?
