Hey guys, I'm pretty new to the game, I've been playing for around 2 days and I've run into as small problem. I keep coming up against the problem of duplicate kerbals piloting my ships. For example; I set Jeb off on a mission to the moon and landed but accidentally jettisoned my engine so he is stuck - I was pleased to have an excuse for a rescue mission. I head back to the assembly and load up another rocket with an extra unmanned pod on but when I prepare for launch I see Jeb is the pilot for this one as well. Of course it seems like a tiny problem to most but I'd just prefer it be another of the pilots. I've also heard that when two duplicate kerbal's get close together one ends up being deleted and I don't want to get all the way back only for one Jeb to disappear. Is there anything I can do in the future to avoid having the same kerbal spawned twice in a row? Thanks in advance.
