I'm glad you like the game! 😊 I'm sorry to hear about the Tamed Bolt breaking the game, do you have any more information about what happens?
I do not remember the setup or what else was preset in deck/field, but the first time i used a newly acquired tamed bolt, the game just froze. This happened the first two times I tried using it after the 3.5.0, however I have tried once again and the tamed bolt worked with no issues, so guessing it was a specific set of circumstances?
