I know I'm beating a dead horse again and again and again. But I keep getting moonstones and no where to use them. I know GP only creates new context for EG. So, do something, anything, in EG, to use them. Two empty buildings there to program. Some kind of game, like you can use coins in Slots. Surely there's enough imagination at PG to figure out something. And since this game has been rumored to be on the back burner, someone would love the challenge to create a creative, fun, extra.
ETA: I feel like taking screenshots of all moonstones and submitting a ticket for refunds. Won't do it, but that's what I think.
