Hello,
so this happened in an Arena game after I played a Flame Elemental and a High Cultist Basaleph when the opponent had in play two secrets from Private Eye. It really happened out of nowhere and if I could provide something else that would help y’all I would be glad to. Interesting thing is that between the first 0-4 minutes, I saw the opponent hovering cards and attacking me, but with just the arrows. I would like to provide screenshots of it, but there is not an option for it (I tried a link and that did not work.
you dced
the moment you notice you need to close and reopen
Oh yeah I know, I did not need the reason for why this happened to me, just wanted to help the devs. But thanks!
Bruh… 
How many years had HS been around? And still they don’t have a better solution than:
“As a tip, if you run into this and realize it soon enough. Immediately force close your game and restart. If you are fast enough, there is a chance you can still reconnect to that game to finish it out.”
Guess you can’t ask much from a small indie company such as Activision/Blizzard
(Yes I just had this issue and had a Nam’s flashback like experience, didn’t close and re-open fast enough tho)
Here’s a Non-solution from blizz: Endless turn, Card Stuck Hovering, and Never Roping
