The autotapper chose the worst possible land to tap to play my sol ring, preventing me from casting the quantum riddler that was exiled from warp. As a result, I lost the game.

My hand was only one card: the sol ring. I had previously warped a quantum riddler. There were no other actions I could have possibly taken after playing the sol ring, other than casting the quantum riddler. The autotapper chose to tap an island to pay for the sol ring, preventing me from casting the quantum riddler. This is a very clear-cut logical situation, it should never decide to tap the blue that prevents me from playing my one playable card.
