Hello,
There is currently a n expansion event going on and the 6th island (Shadow one in the bottom right corner) is available for 25 gems on my device. I have the gems and already tried to buy it ~3 times.
Every time i buy it, it gives a crash message: "Something didn´t work. Please restart your game"
I can´t seem to make the purchase work, even after restarting the game multiple times.
