I had a mission with two Kerbals who ran out of oxygen, food, and water, and due to having hibernation on, they became tourists for the duration of the mission. However, since recovery of the craft, I can no longer use the kerbals (one former pilot, one former scientist) for their intended roles, despite adding food, water, oxygen, and sufficient waste capacity to a new craft. It appears the only way to fix this is through editing the game files- is there anything I'm missing?
