Yeah, waiting 8 hours each time you finish with a stone is a bit much. I understand waiting until the timer of the stone itself finishes, but why do we have to wait 8 hours before we start a new one? What could easily be done in 6 hours is turned into 16 hours of waiting total and 2 hours for each stones, so 22 hours.
The server times have already changed to accommodate you guys. Gave the players that have been playing GMS on PST for 10 years the middle finger. The devs aren't gonna come in the middle in the night to accommodate you guys even more. It's in the middle of the day for us and you don't hear us complain.
