What do I do if my Sims Freeplay quest just stops?

I have the Sims Freeplay app on my iPhone and I was doing the Christmas quest where you can get a pet reindeer and as I completed goals, I'd get new ones. But then I just stopped getting goals and Santa disappeared and I don't got a reindeer yet. I haven't even found the third elf! I can still go to the workshop and the two elves I already found are there but I can't do anything with them and Santa isn't there or in my Sims' homes anymore. I only have seven days to complete the rest! How do I get the goals to resume?!

Added (1). I did seven days worth of goals in a few hours (I knew I was behind so I used LP to skip the ones that would take four hours or whatever because i never use LP and had it stored up) so I wasn't sure why I wasn't getting any more goals when I wasn't made to wait for the next day's goal before. I got the nutcracker - I finished that day. I just haven't gotten the goal to "Admire Nutcracker" yet.
