Hello @Alienscar, I buy the gold bars when the piggy bank is full. I use the gold bars to get an extended play. They also took away hard levels which are marked by the 💀. Those games allow you to earn gold bars for purchase when the "chronicle" is full. I noticed this morning that they put the hard levels back.
I updated my game and there is still no piggy bank or hard levels to earn gold bars. The only way you can get gold bars is if you pay for them. So unfair.
