It took me a year to collect 97 gems, just three more days and I could have unlocked the next island but accidentally spent all of them to create a new crystal in the ancient world, is there a way to undo it?

Hi and welcome to forum :)

you can send a support ticket about this to sp , asking them to take the new crystal back and refund you , this is how to contact them

@Sarah-Motionless-Easley I think we have all done something similar. You can try sending a ticket to support but don’t hold out a lot of hope. Especially since there is a confirmation button.

To avoid accidental spending in the future check your setting and “enable” the confirmation for spending more than 20 gems.

@LilCricketPa
IIrc i read here many times that gem confirmation doesn't cover ancient world, is this changed now ?

@Haka-Taka Confirmation button still doesn`t work for Ancient World. People can spend lots of gems accidently by tapping quickly.

@Haka-Taka I was not aware that it was still an issue. That really defeats the whole purpose of the confirmation button then since it was the problems with ancient world that caused the complaints to begin with.

I think everyone mistakenly spent gems there. It was really easy to do. Get hit with a little lag, next thing your out 100 gems.
