ItemProductPrototype#amount states that amount should be a uint16:

amount :: uint16

but doing a --dump-data shows a fractional amount for some recipes in data-raw-dump.json. EG:

Code: Select all

"uranium-cannon-shell-recycling": 
    {
      "type": "recipe",
      "category": "recycling",
      "results": 
      [        
        {
          "type": "item",
          "name": "cannon-shell",
          "amount": 0.25,
          "extra_count_fraction": 0.25
        }, ...

It seems to affect recycling recipes where "extra_count_fraction" > 0.

This is hard to classify because what you see is raw data without any rules enforced that would get applied when creating prototype instances. There may be also leftovers from data stage if mods put some data that are unused by the game itself. Fixing this would be like plugging a single hole in a colander.
