All social tasks show as incomplete even though my sims completed the actions

I am having the same problem. I have uninstalled and reinstalled the game and that didn't correct it. My social point tasks stopped working when it got to the "catnap in a neighbor's house" task. I am now unable to earn any social points. I've tried repeatedly to complete the task in various houses or at different times and it didn't work. I finally skipped the task thinking it was a glitch (as the person above said), but the next task was stuck too. I've now skipped two and a third is stuck, and I refuse to waste any more LP on it. I've already invested $30 into LP and XP, and I don't want to spend any more money. Unfortunately I also won't be able to progress in the game without social points, so at this point I've just wasted money on a game I can't complete. Please help.
