Lost everything. Event just disappeared

Played my last two 30 minutes before the end time. 10 min. Later i decided to look if i was still in leader 1000 position. All of a sudden the game ended giving me the 1000 coins. Then something came on the screen saying something about a special bonus of sorts 999 and the screen froze nothing happened. Then the game restarted and when it started again the wvent had gone away. I lost all my red coins that i played all week for and i didnt get the new tranformer.
