  1. Bug description
    [Describe what the bug is in your own words.]
    When trying to start a game with skill cards in a deck the game says “Invalid amount of Skill Card Name” despite the skill cards option being ticked in settings and card pool set to All. This is happening for everyone in my playgroup and certain players are also saying it’s happening to some other cards including Poison Mummy. It was working fine when we had our weekly session on Thursday but was broken by Monday.
