Rupture Spire + Blood Sun soft-lock [Investigating]

Ark Posts: 20 Just Dropped In
I'm really not fully aware of what caused this soft-lock, but it's some interaction with Rupture Spire.

Battle Log

Turn 10 (opponent's turn)

And then the game soft-locks. It seems like the game soft-locked after the Rupture Spire cast and the board is stuck in this state where all of the gems of my opponent's colors (R/G/B) are destroyed, but the cascade isn't happening. The board is just frozen with all of the voids from where the gems used to be.
