In the middle of my last game, my friendly minions were off-center, clipping to the right side of the UI. My friendly minions also would not move when I hovered a minion over my playfield. I also happened to have a Selfless Hero on my last round that had Reborn for some reason. Selfless Hero returned to my playfield after dying, but it did not play again, as it looked like it was my last minion standing, but I lost anyways with it still on my playfield.
