It was installed on a separate hard drive. I tried as you suggested and created a new Steam directory in my C:\Games folder. I then installed KSP and the Mechjeb mod. Everything is the same: Mk16 parachute picture is missing in R&D tree. Am I the only one not seeing this? If so, how could I be replicating this problem if I'm reinstalling? MechJeb is present and working in Sandbox mox. MechJeb is nowhere to be found in Career mode. No parts, no mention of it in R&D. This is really frustrating.
