Just as every game works there is a time limit that you have to wait before a job is finished. Waiting this time is a bit annoying and it makes the game feel very slow at times. To complete this glitch you can go to your phone’s time settings and set your phone however long the longest job will take you ahead. Enter the app again and make sure everything went fine then you can go back and reset the time to the proper time so you don’t forget to do it later on. This also works for refreshing your energy and it comes in handy a lot of the times. This glitch is harmless and won’t hurt you or anything that the game has to offer.
