Merge acadamy -- Treasure Trove

Anybody having issues with saving the progress in Treasure Trove?

I was playing the game, and used up the existing energy.

I then "bought" 250 energy using the gems.   After I  used up those 250 energy, I went back to the original game,.... and an hour later, was back to  the ORIGINAL point before I  bought the energy.

I now have to start all over,  AND am out 50 gems!!!!!
