This just happened to me twice in the 'Attack of the War Monkeys' adventure. One of the monkeys pickpocketed my character and stole a card. They attacked with that stolen card, and the damage was blocked by Inspiring Armor. This caused the game to freeze, with the attack (different both times) and Inspiring Armor remaining in the middle of the screen. It seems related to Inspiring Armor drawing when you take damage from 'an enemy controlled card', and the card here was not an enemy card. I believe in both cases the card was stolen from the same character who blocked the damage with Inspiring Armor, but I don't remember for sure on the first instance. This happened in CardHunter Version 2.92.0.10025, SFS Version 1.2.0, the browser is Chrome version 39.0.2171.99 m. Unrelated note, in your 'How to report bugs' thread, you should mention the F1 log earlier in the thread. I refreshed the page trying to find the version of the game before seeing the bit about the log, so I don't have that to add here.
