Same problem. I’ve done like 7 or more diamond activations, and it only worked once. That is totally NOT acceptable in an incremental idle game. That MUST be fixed SOON if you want this game to survive. Drop everything else and fix it – it’s that critical.
And just to make things worse, ANY attempt to use an import is an automatic HARD reset. So not only did I not recover the potential diamonds I DIDN’T get from my soft reset, I LOST the few pathetic diamonds I DID have working from the one time it worked. TOTALLY NOT COOL MAN.
