Just a heads up should you enable this mod mid-save with mining productivity already researched. The bonus production you researched before stays on drills even with the Fracking Tower mod enabled. Not sure if it can be disabled thru the mod, but I would probably mention it at least in the info.

Great idea and mod btw! :)

Yes, that makes sense. I could reset the mining productivity, but I would rather let the player do that with a command. (Plus, if I reset the productivity, it's fragile if someone wants to mod in both fracking towers and mining prod research).

I think this command should work:
/c game.player.force.mining_drlll_productivity_bonus = 0
although I haven't tested it.

It could be nice to have a mod setting to reset productivity research so that achievements don't get disabled by using a command.
