I lost 25 stars in the raccoon challenge, how do i get them back?

Hello @Amanda_Clause, Hearty Welcome to the Candy Friends section of our friendly King Community  

Oh my!!!  That is very sad and does not sound right   Especially, since the event is ending in few hours!!!  

By any chance, did you take screenshots of the progress of your Star Chaser?  If you did, you do not have to worry at all as the Team can take care of it   If you have not taken any screenshots of the progress, then I am not sure how they can help you!!!  

In the mean time, keep trying to gain as many stars as possible since the time of the event is very less!!  The Community Manager for Friends will be back tomorrow!  We can request what they can do for you!!  

Please post back and let me know, so that I can take further details from you. 

Keep trying for all those Stars.  All the Best & talk to you soon!
