prize booth challenge disappeared

I was at silver prize booth and then my game restarted. I didn't see it when I logged back in, so I followed the advice published before and played several more levels with no change or update. since it depends on passing new levels, i am concerned about playing further since I am almost out of levels. please advise on how I should proceed to ensure that I have enough levels to reach the gold booth I had 3 levels past silver tier when the game rebooted and only have 24 levels left. the game showed that i have to pass 21 more levels to advance to gold booth.
