So first I think there is a mistake in the listing. Ore Productions, Bar Productions, and Item Productions are all the same. They're all @ 64%; FIVE 10% techs and 14% for my Mine Boost Artifact. All those should only effect Ore Productions, not Bar or Item Productions. Bar and Items should be effected by speedy smelter/crafter tech and Artifacts, so I'm pretty sure this is wrong.
Army Camp Production does not list the 20% bonus from watching ads.
Digging Speed is listed. How do you increase digging speed? Would really like to know.
