I'm at level 22 and the Geologist is getting properly annoying now. When I log on after sleeping and working, all my mines have depleted, so I have to search for them again. I have 4 stone quarries (4 min each), 2 bronze mines (10min each), 3 marble quarries (30min each), 2 iron mines (1hour each) and a coal mine (4hours each). To search for these deposits again, it would take 8 hours and 6 minutes total (and that's even without a goldmine). Because the geologist is too stupid to take multiple orders, I'd have to stay behind the computer for that time or come back every couple of minutes during that time in order to keep him going. That's impossible for people with regular jobs and also something called a life. If, like me, you only have an hour or 2 a day to play the game per day, it's impossible to keep it up.
It's time therefore to introduce the smart geologist who has a search queue, so you can select multiple resources for him to search. If not, you will lose another player (I'm sure others have quit the game for this reason.
