So I'm having loads of fun with this playing career mode, but I ran across a problem. I went to Minmus, got there just fine. While I was diving towards the Pe of 10km, suddenly Mun happened. It seems that Minmus SoI crosses Mun SoI. I got thrown off in a random direction, instead of keeping my previous speed relative to Kerbin, which was weird. You might have intended the SoIs crossing eachother, but it seems KSP can't really handle it well. Or rather, at all. :<
