Shifting Scroll into Explosive Runes bug (Anomaly Mode!)

TL;DR Game is stuck after the opponent activated an Explosive Runes (previously a Shifting Scroll) in Anomaly Mode

I was playing as Eudora against Sinclari in the Violet Hold (anomaly mode: all spells cost 2 less). On turn 5 I played a Vicious Fledgling, then killed my opponent’s Flamewalker with WANTED!. I used the Coin I got from WANTED! to play the (1) mana Explosive Runes (previously a Shifting Scroll). On the enemy’s turn, she Fireballed my Fledgling, then played a Kirin Tor Guard, which activated my Explosive Runes. The Guard died, but the game wouldn’t progress past that point.

This is in the known issues list at the top of this forum:

When that happens, you can force-quit the game (Alt+F4 in Windows) and restart it to return to the game in progress. There is a small chance that it won’t work, but better than loosing your run.
