I was watching Baduru vs Zaladar live match. (xystus vs theFourSeasons)
Baduru stole Der'kan from Zaladar's hand via Night Prowler.

First picture was what happened when my cursor hovered over stolen Der'kan in Baduru's hand.

And this was when I clicked on that Der'kan.

All of this happened after stolen Der'kan was killed and returned to Baduru hand.
Not sure whether zaladar's player could see this.

I went back to watch the match again before posting this and found it also happened when viewing replay.
