Thank you for quick answer. I can do everything except upgrading - I will loose all booster and gold. First I need to use them all. Restarting phone didn't help. I can leave with that crushing. This may be extra challenge. 😎
I figure it out they still on my account if I log directly thru Facebook. Yes, looks like there are stored on server, while application game store in my device. Thank you for all responses. It was very helpful.
Thank you for quick response. It's sad, but I understand. I just collect them in last few days while playing, not purchased. So... I guess the best way is use them on-going before next game update.
