Headless server expensive recipes?

[Blahbla]

TL;DR How do I make recipes expensive on my headless server?

Cheers.

In map-gen-settings.json of 0.15.28, there are three fields for difficulty:

Code: Select all

"difficulty_settings":
{
   "recipe_difficulty": 1,
   "technology_difficulty": 1,
   "technology_price_multiplier": 1
}

I meant for my headless server to use "expensive" mode for both recipe and technology, but I don't know what values to use. Setting "recipe_difficulty" or "technology_difficulty" to 2 produces an error when trying to generate the map (something like "unkown recipe value"). Setting them to 0 doesn't produce the error, but the recipe cost remains normal.

I found a dumb workaround: use single player to create the save file, then tell the headless server to use that save.
