HEYY guys I've read some of your entry's and I've found a cheat!
1. Go on your my sims app and buy as many garden patches as you will need for one per sim.
2. Make all the ADULT sims in your town plant beans.
3. Go off the app and when you reach the main screen double press your home button and a multitasking bar will pop up.
4. You will see the sims freeplay app press and hold on it (as if you would delete) and press the small red circle.
5. Advance to your settings and switch off automatic time
6. Change the date to 1st June or July 1985
7. Repeat step four and five.
8. Go on to my sims and collect the beans you will have lots of money!
I hope it worked for u xxx
