So I upgraded my PC recently, and moved save files to a new clean install of Win7 and KSP. Now when I load my save and enter the VAB, the parts list appears but the categories to the left of the parts are missing, and whenever a part is selected it just jumps to the center of the floor. Parts on existing craft cannot be selected. This occurs with and without mods. Here's the odd bit: if I load a new career save, everything works correctly, and if I load my old save afterwards, everything works! Now if I load the old save first on booting up KSP, the vab will break, and will also be broken in the NEW save if I switch save files without restarting the game. I guess this is technically a workaround, but it's a pain in the backside to have to load two save files every time I start the game. Does anyone have any thoughts?
