Hello.
I have been playing around with your mod and it's pretty useful. Though there is one complaint i have though. The compressed coal stacks are ridiculous as they can go up to a few thousand (10,000 i think). That makes it almost feel like cheating and when you try to quick stack them to furnaces the whole stack goes to the furnace so you have to manually add it.
I propose that you make them stack like normal coal or a bit more like to a hundred since they are already compressed.
Well just an idea, but i feel like that would fit into the game a bit better and be more realistic.
