The BGH is only available on weekends. Even this event is only given to selected groups of players and not all players have it. I hope this helps you further.
Hy! I didn't receive my rewards in bubblegum hill at least 10 times this weekend. Also having problems with network connection. And my network is very very good. Only Candy Soda doesn't work.
Another note: BGH is currently having problems with the rewards. We are already working on this. There is a big contribution about it. Would you like to read through !!! Hope this helps you a little further !!!
