I’m trying to add a couple of vehicle-mounted railguns to my ForkIt mod, but it’s having trouble with this one type of ammunition, which is the default one. The guns definition: { “id”: “emrail”, “copy-from”: “rifle\_semi”, “looks\_like”: “m2browning”, “type”: “GUN”, “name”: { “str\_sp”: “electromagnetic railgun” }, “description”: “A mass driver that uses electromagnets to drive a sled on rails carrying a heavy payload, and launch the payload at high speed much like a slingshot. The sled is designed to carry payloads of a wide variety of shapes and sizes, up to about 20kg. Too heavy to be fired handheld, but can be mounted on a vehicle. Powered by UPS, and consumes 150 charges per shot.”, “weight”: “38000 g”, “volume”: “9020 ml”, “longest\_side”: “165 cm”, “price”: 1800000, “price\_postapoc”: 10000, “to\_hit”: -1, “bashing”: 12, “material”: [“steel”], “ammo”: [“rebar\_bolt”], “range”: 110, “dispersion”: 150, “durability”: 8, “min\_cycle\_recoil”: 5, “reload”: 250, “ups\_charges”: 150, “modes”: [[ “DEFAULT”, “semi-auto”, 1] ], “flags”: [“MOUNTED\_GUN”], “pocket\_data”: [ { “pocket\_type”: “MAGAZINE”, “ammo\_restriction”: { “rebar\_bolt”: 1 } } ] }, { “id”: “pnrail”, “copy-from”: “rifle\_semi”, “looks\_like”: “m2browning”, “type”: “GUN”, “name”: { “str\_sp”: “pneumatic railgun” }, “description”: “A mass driver that uses compressed air stored by a high-pressure pump to drive a sled on rails carrying a heavy payload, and launch the payload at high speed much like a slingshot.

It also gives a “missing item definition” error, but doesn’t say what item.
