Not tested with stone, but iron and coal do reach a limit.

Thank you Tina

Awesome, thanks

2023 update if anyone cares. This mod is still working and also works with the 7 part Mega Mod but only seems to work on the vanilla buildings. You must move it to the top of the mod list when enabling all of them for it to work correctly

i know this makes the mines and quarries OP but i will download it anyways thx for the effort

Based mod,is just what I need and desire .

sweet thanks!
