can you add a fast_replaceable_group to the chemical plants?
you can do it by putting the following code to the data-final-fixes.lua
-- set fast_replaceable_group for chemical plants
-- set fast_replaceable_group for base chemical plant if not available
if data.raw["assembling-machine"]["chemical-plant"].fast_replaceable_group == nil then
data.raw["assembling-machine"]["chemical-plant"].fast_replaceable_group = "chemical-plant"
end
-- set fast_replaceable_group for new chemical plants to the one from base game
data.raw["assembling-machine"]["chemical-plant-2"].fast_replaceable_group = data.raw["assembling-machine"]["chemical-plant"].fast_replaceable_group
data.raw["assembling-machine"]["chemical-plant-3"].fast_replaceable_group = data.raw["assembling-machine"]["chemical-plant"].fast_replaceable_group
