Several times I have experienced a GreError crash that results in a Draw when I’ve had several Mirror Reslm/Fractured Realm (from Extravagant Replication) fully unlocked and an effect triggers. The latest trigger was five Overlord of the Hauntwoods attacking, and I had four Fractured Realm, which would be five triggers each for a total of 25 triggers. Not a huge number, but the game crashes. It’s probably happened four times.
