When loaded by itself, no problem. But when combined with True Nukes continued, received the following error message at startup:
Failed to load mods:Warheads_Continued/prototypes/weapontype-sanitise.lua:243:attempt to index field 'ammo_type' (a nil value)
stack traceback:

Tried loading without K2, K2 assets, or K2 menu simulations and works fine, so some sort of incompatibility is my guess but no idea
