I'm on a PC. I'm playing a Shrine deck (standard). I had a the Stone Fangs (black) and Calm Waters (blue) Shrines down. Between the two triggers I got an error message on the screen each time. I didn't note any problems with the game, just the error popping up. If I didn't have the blue shrine trigger after the black shrine, I didn't get the error at all.
Also, a second minor bug - on the Ikora battlefield, once the stone monoliths are broken and fall apart, the two large crystals no longer make crystal sounds, they make rock sounds.
