Not sure if this is a bug, or I am just using MechJeb wrong.
MechJeb will get me to to space, then it just will pass right by the node it needs to circularize. (I don't have skip circulation selected)
It seems as though the only function that works for me is the Assent even though I have researched Unmanned tech and all other MechJeb tech (except rovers).
I have used MechJeb in the past but on earlier versions and never experienced this, hence why I'm not sure it's a bug or not.
I'm going to try to remove all my mods and do a fresh install.
