Greetings!
I've encountered an odd bug while playing Duck Racing against a bot earlier. It used a challenge on me and we blackjacked. It tried to draw a card and busted, causing it to lose its feathers. It froze, and I guess the game decided it felt left out so it decided to freeze with the bot. :D
More seriously, I basically could not do a single thing afterward, it froze on the blackjack challenge. No space, escape, backspace or anything could get it to go back to normal. Here is a log.
Cheers!
