I´m updating the customizable engines mod but this always happens with pigeon and t-series - vehicle doesn´t spawn and the console says: "unable to decode json... ...invalid input at line 62" it doesnť matter what is on line 62 ,it always happens. I tried clearing cache, disabling all other mods and even completely re-doing the jbeam but nothing helped.
You had an extra [ in the middle. Try it now. i think it should work --- Post updated --- Semi had some more stuff that i didnt see at first.
