So, I don't know what's going on here, but I have the following mods installed: Kethane Interstellar SafeChute Enhanced Navball Atmospheric Sound Enhancement Docking Port Alignment Kerbal Alarm Clock KErbal Joint reinforcement Visual enhancements And these all work fine and dandy, but as soon as I install FAR, it breaks the tech tree in career mode, and as soon as I remove FAR, the tech tree works again.
