This mod and the AWG WeaponCore Pack appear to be mutually exclusive where the Khanda Heavy Railgun is concerned -- the railgun is inert in the WeaponCore pack, which causes a conflict with this mod. Regardless of mod load order, if both of these mods are in your world, as soon as the railgun is placed, the space weapons will all stop working (along with various other WeaponCore-dependent mods, such as the MCRN PDC Turret ).
