My game crashed after I cast Verdant Mastery and Roaring Earth got destroyed. In the battle log is shown that Roaring Earth got destroyed. On the battlefield only the spinning circle is visible and the empty spaces of the gems that got matched by Verdant Mastery.
Also happens when The Kami War is popped. I’ve noticed it would pop when it still has 2 shields. Same result.
sounds like a variant of this https://forums.505go.com/discussion/86810/soft-lock-on-support-destruction-investigating#
