Details: According to the encyclopedia, an Ultra Deep Dig Site produces 1.44/artifacts per min with all workers in a site. I have 24 such sites. I have timed this several times now, and I am producing around 6/min total (for all 24 sites). This is obviously a significant difference, as I should produce around 35/min. This is dragging everything. I have checked all of the sites, and they are each fully staffed at 60 workers. Please advise and fix.
Sorry for logging this incorrectly the 1st time. Hopefully I have all the information you requested.
Additional edit: I checked the resource statistics. I have no drains on artifacts. I have three (3) Ancient Alien Semiconductor buildings, but those are deactivated, and have been deactivated for over several hours of play and an actual calendar day. Even when activated (on previous tests), it did not seem to significantly alter production. But, I have no means of producing precise numbers (that I am aware). I have done 5 stop-watch tests to produce these numbers that I submitted.
