Hey guys, been playing KSP 1.0 for some time now and I started building a Mun Base - but all of a sudden, I can't add new modules because the docking nodes refuse to work! There is no magnetic pull and even if they are (visually) perfectly aligned, the module won't dock! Is this a know bug? Did I break something? I am running the latest version with the following mods: Chatterer PlanetShine Kerbal Engineer Infernal Robotics Can anyone help?
