Encountered this error when Crushing Industry and Cupric Asteroids are present alongside bzsilicon:

Failed to load mods: Error while loading recipe prototype "sand" (recipe): In RecipePrototype, category and additional_categories got merged into categories table. Please use that instead.

Of the above mods, confirmed the error is indeed coming from bzsilicon: https://github.com/brevven/silicon/blob/master/recipe-updates.lua#L284

284 > data.raw.recipe["sand"].category = util.k2() and "kr-crushing" or "basic-crushing"

as changing it to this allowed the game to load:

284 > data.raw.recipe["sand"].categories = util.k2() and { "kr-crushing", } or { "basic-crushing, }"
