One of the most annoying things to me was the time factor -- you had to wait for EVERYTHING. However, I discovered time is device-side, even though the rest of the game is server-side. So if it takes four hours to finish building a house, for example, simply turn off the auto network time on your device and advance the time by four hours. Reopen the game, and wala! The building is finished. After you're done playing, even if you're months in the future, just turn network time on again, and you're good. The gameplay does not revert back, so all your progress using the time exploit is kept! Hope this helps!
