I've faced with this issue when I'm playing Sins of the Saviors (Underneath Sandpoint 5-1) second difficulty level.
The scenario condition is that upon defeating monster, I'll need to role for Stealth check; otherwise face with Hound of Lamashtu.
After failing the Stealth check, upon facing the Hound of Lamashtu there's a Wisdom check to determine the increase difficulty level of the monster. After rolling the dice, the screen stuck there with the message "Rol!" but there isn't anything to roll.
So I can't proceed with playing, even after I forfeit and replaying that scenario.
Another issue I've faced is that the reward for clearing (5-5) Runeforged Weapon. After clearing that scenario, the weapon doesn't appear in the card selection list. Even the Christmas event gift "Festive Wool Hide" doesn't appear in my card list, hence I can't select any of those cards.
I really appreciate your team's effort in fixing the game for us and I'm looking forward for these fixes. Thank you!
