Noticed that recycling mk2 beacons doesn't give any superconductors but I am getting copper wire which is not in the crafting recipe. Used recipe browsing mod to check the recycling recipe and it seems to have materials for non space age version of the recipe.

I made a small mod with dependency on your mod and data-updates.lua with

local recycling = require("recycler.recycling")
recycling.generate_recycling_recipe(data.raw.recipe["wr-beacon-2"])
recycling.generate_recycling_recipe(data.raw.recipe["wr-beacon-3"])

in it and that seemed to fix the issue. I have no expierence in lua programming so I have no idea if that was the right way to do it but simple fix in any case.
edit: the forums turned recycler with 2 _ on either side into a bolded text

Thanks for the report, it's fixed now.
