Hello,

only a little issue. My datapack from 16.0.6/7 don't functioned 100% in 16.0.8.

First i deactivate the old recipes from wood tank

fluidtank/recipies/tank_wood.json and tank_wood_easy.json => 0 bytes.

The i implement the harder recipie:

harder-recipes/recipies/tank_wood.json

In the older versions tank_wood.json will be nulled and deactivated and only my new harder recipie will be used. Since 16.0.8 he don't null the original recipie and take both recipies original and harder.

?

It's not allowed to remove recipe by replacing with 0 byte file. As you see, you'll get Couldn't parse data file fluidtank:tank_wood from fluidtank:recipes/tank_wood.json or some errors.
It's fine to override the recipe with your own recipe. Save it to fluidtank/recipies/tank_wood.json.

If you want to disable recipe, put this to fluidtank/recipies/tank_wood.json

{
  "type": "fluidtank:crafting_grade_up",
  "tier": "silver",
  "sub_item": {
    "tag": "forge:ingots/silver"
  },
  "conditions": [
    {
      "type": "forge:false"
    }
  ]
}

(The recipe type or silver doesn't matter. forge:false in condition will prevent this file being loaded.)

BTW, you can disable all tank recipe by changing RemoveRecipe in config to true.

Also, in my environment with these mods, datapacks correctly override recipes. As you know, I was working on an issue with mixin and I made no change in recipe system(I'm using vanilla system modified by forge).

Ah okay Thx. Seems like zerobyte-jsons only work 15,x and lower. The HarderFluidTank-Datapack ist the first that i use in 1.16:). Functioned very well with the forge condition. Thx.
