This Glitch doesn't get you a ton of lps at once but it does work!
1) Enter the sims free play app
2) Double tap on the home button and go into you settings (make sure the sims app and settings are the only things in your history)
3) Go into date and time (in general)
4) If it's not already make sure it's on set automatically
5)Then change date to October 23, 2015 (It has to be that exact date. Don't know why??!! xD)
6)Double tap on home button and delete the sims free play app from your history
7)Go back into the sims free play app and you should get 20,000 simoleans, and 2 lp
8)this glitch also speeds up quests, and once and a while construction
