I have found that I can add tokens and damage to a card that has been sent to the discard but i cannot remove them. The first time I did this in a game with a friend it crashed the program. I attempted to replicate the crash, but it did not crash the program this time. I am unable to remove the token or damage while the card is in the discard, but it appears the crash was a fluke. I tried both by hosting and playing single to see if that mattered. I'm not sure if the fact that you can add tokens and damage in the discard but not remove is by design or incidental, but I wanted to make sure I reported it for you.
