500 hrs to build!!!!!

My to do task is to build 4 work places and I'm building a fire station but it's 500 hrs. And I need 90 lp to seed it up! I've tried skipping the date to 1239 but it still doesn't work! Any help?

you could try this, go to ur settings and turn it on auto then go to the game have ur sims doing something the go back to settings before you do anything on settings double click the home button and do the thing you would to delete but only on the little bar at the bottom for the sims then in settings turn on the manual for date and time then go about 7 years, days, months forward all of them then go back to the game and it should be done.

It worked but my sims are still planting with 21h to go! :-/
