Yes, you are reading this well. With this mod I have the weirdest bug : when placing a pumpjack on a oil patch, it produces x/s of crude oil, BUT also x/s of stone.
I've checked reddit, the threads here, nothing. I can tell it's this mod cause when my mouse is over an oil patch, it tells the mods affecting this data, and the only one is quarry.
Do you have a workaround ?
