place stacksize manipulation within config-dependent branch of code as since, currently, they overwrite anything set by wormmus or noxy's or other stacksize altering mods.

currently, i just did this to fix for my current game:

if true == false then --jacks up wormmus or noxys or any of the other mods that alter stack sizes.
-- Stack Sizes
data.raw.item["iron-plate"].stack_size = 200
data.raw.item["copper-plate"].stack_size = 200
data.raw.item["steel-plate"].stack_size = 200
data.raw.item["coal"].stack_size = 200
data.raw.item["uranium-ore"].stack_size = 200
data.raw.item["sulfur"].stack_size = 200

--data.raw.item["empty-barrel"].stack_size = 20
--data.raw.item["crude-oil-barrel"].stack_size = 20
data.raw.item["raw-wood"].stack_size = 100
data.raw.item["wood"].stack_size = 200

end
