Have an issue when all granite deposits (6) empty when i log in. Send 6 geo's out whilst doing other stuff on island approx 1 hour, then either log off or leave game running. When I come back only 1 or 2 granite deposits found and all geo's back. If i am logged in to game and a geo comes back he finds a deposit. This has been happening about 4 days now and i have been watching the geo's more closely as i usually like most players fire and forget geo's/explorers.
