I used this cheat on the 31st of January right after I updated the game. It seemed to have worked fine. The next day I thought that I would try the same thing and that's when chaos ensued. The Party Boat and Competition Center are both at astronomical numbers. In order to get the Party Boat gift, compete at the Competition Center, send my Sims to work and pre-teens to school, I have to set my iPad 2 time to December 27+, 2013.
Every time I collect the Party Boat award, the collection time moves back even further when I change the time back to my real time. I wish that I could wait a whole year before sending my Sims to do things, but that's the part I love most about this game. I backed up my game to the iCloud on the 26th of January. So I have to revert back to that.
Unfortunately, I lose the money that I paid for with real dollars, the money I siphoned from the cheat, 5 Sims with jobs, hobbies, and relationships/friendships, the remaining construction of the workplaces and stores, an infant, the remodeling of ALL of the homes, and 5 levels. *sigh* That was a run-on sentence there. The cheat that worked before the update (going back to 2009) is now the direct opposite. When you went back in time that gave the you $ and exp. from the buildings, etc. Then you could go back to real time and everything would be fine. But the cheat that works after this new update, your REAL TIME is like 2009 minus the $ and everything.
Sure, you can go to December 23+, 2013 and get everything but when you come back to your real time, the Party Boat and Competition Center is out of order. You then have to revert back to December to send your Sims to work and so on. I hope I make sense, but I'm sorry if I do not. I don't know about Android, but if you have an Apple product be sure that you save your data daily if at all possible. If there has been a new development that I'm not aware of, please let all of us know.
