I've created a fully powered beacon (correctly as it displays all the powers and works) and I can still unlock achievements in my world as I've never turned cheats on but it's been a couple hours and I still don't have the beaconator achievement. I've tried replacing the pyramid, the beacon, tried using all primary and secondary powers (a waste of a lot of mineral resources) and it's still not showing up as unlocked. I did some research and found that this is a common problem so please fix this!!
