I have found that the production count in the quest does not match what is happening in game.
Specifically, I produce water now at 51k/12 hr but after 3 hours the quest registers only 1k produced. It should have taken less than 2 hours to produce the required 7500 water according to Economy Overview. It is on pace to complete in about 20 hours according to the Quest log.
Yes, I turned all production facilities off and on again after buffing them. Roughly, it seems to only count Watermill and Improved Watermill, not Wells.
Ideas?
