First time trying out the mod. I get the following error when it tries to load:

Failed to load mods: Error while loading recipe prototype "locomotive-mk3" (recipe): IngredientPrototype must be a dictionary and contain "type" property.
Shorthand format using an array is no longer supported in property tree at ROOT.recipe.locomotive-mk3.ingredients[4]
Modifications: Better Train System

Can I have your modlist? Maybe some other mod is modifying stuff around

Hi. I always appreciate the work modders do. After your suggestion I realised I could investigate that for you and save you doing it. I disabled all mods and reenabled them until I got to the culprit, which is Electric Trains by Degraine. I can load all of my other mods alongside yours without it. I've disabled ET for now and will keep yours active, as I need to go to another planet to make use of ET anyway.

I look forward to playing with your mod and hopefully the future compatibility with ET. Thank you!

Solved with new release
