My Lands: Black Gem Hunting

twoo villages show low production on stone quarries. all buildings are filled with workers. three quarries show production 30/hour and four show 2/hour. what's going on?

Point to the quarry and check the deposit of the resourse, you've possibly mined it all.
If so have to destroy the stone quarry and build over it - Flower of Plethora
to restore the deposits.

i just got a meesage, depleted, as you say. my city is five days old, how can it be depleted already??? this must be a glitch!!! is there anyone who can fix this? or am i just screwed?

Probably it's depleted because someone else had a city there before you, and he mined the resources.
