Some of the parts don't load for me: the workshop, the launchpad for the space stations, any of the larger part tanks, and the steaks. The mods I have are: Module manager, KIS, Kerbal Joint Reinforcement, infernal robotics, modular fuel tanks, Near future: electrical, propulsion, solar, and space craft, mechjeb2, OPT1, and planetary base.
I am on a mac (I have a windows mode, have not tried it) v 10.11.3, and using ksp 1.0.5
Any idea how to fix it?
