I've used MechJeb before, so when I came back from a long hiatus to check out .22, I was excited to get MJ installed. However, I'm having a problem using the module in career mode. Several people have mentioned this issue, but I can't seem to find a satisfactory answer. - Start a career mode save - cheat, steal, and otherwise claw my way to researching Flight Controls (which I believe is supposed to be the first MechJeb tech) - Enter VAB to install MechJeb but find that the module must be researched individually. - Enter research building, and click to icon for MechJeb (within Flight Controls) and confirm that I want to research it. Yay! - Enter VAB to install MechJeb but find it "greyed out" and it just has the same message - Enter research building, and the dumb thing is unresearched again. Click, confirm, rinse repeat I've gone through this on multiple saves and up to 3-5 trips between the VAB and research building. What am I missing? Am I researching it wrong? Am I just stupid? Is the answer to this problem somewhere else and I've just missed it? HALP!
