You can change your lost card?? How did I miss that rule
Yes you can, page 17 of the rulebook:
Short rest: During the cleanup step of a round, a player can perform a short rest. This allows that player
to immediately shuffle his or her discard pile and randomly place one of the cards in the lost pile, then
return the rest of the discarded cards to his or her hand. If the player would like to instead keep the
card that was randomly lost, he or she can choose to suffer 1 damage and randomly lose a different
discarded card, but this can only be done once per rest.
