A Factorio industrial overhaul with true orefields, real ore processing, metallurgy, hydrometallurgy, petrochemistry, catalysts, gases, waste handling, and advanced materials.
So far I've noticed the ore sorter and crusher only have shadows if they are working.
Also unrelated but when coke is backed up on the top side of a belt going right or left there seems to be a visual bug where it causes flashing/strobing of the belt in the gaps between the coke icons.
