Every so often, the game just crashes while interacting with the cards in my hand. I've had it happen while dragging a card then dragging it back to the hand as i changed my mind. Most recently it just crashed when moving the mouse over a card. Not sure how i can find more information about this. It's happened four times now in about 10 hours of play.
I'm really not sure it just seems to happen randomly while interacting with the cards in my hand. There doesn't seem to be any specific card that triggers it. It's happened at least once with each character, and in both negotiation and battle.
I had a look at the log (log.txt is all i found that looked relevant?) and it seems to just cut off in the middle of a line. In the one i'm attaching it's logging details about a negotiation, but... i was in a battle when the crash occurred. In this case i had just done the negotiation with the Easies to get them to break Enit the bouncer out of jail near the start of Smith's story. Then it crashed during the battle at the jail as i was hovering over a card to play.
