One day I went onto creative and my rank was gone, it used to be architect but now im veteran. I know your able to change the account back. I have proof of my old account because of how many plots I have (in image in chat, I have 17 plots.)
Your rank is gone because realms and creative merged a couple months ago. Now, instead of the previous ranks (Mason, Architect, Constructor), we have the realms ranks (iron, gold, diamond, emerald, etc). You can request to be given the equivalent rank to Architect, which is Diamond I believe. To request your rank, just email support at firstname.lastname@example.org. Thanks!
Rolled out some small nerfs to the powercore, it's was a bit too OP. The money event will give 10k instead of 15k, the giant gives 5 spawner keys instead of 6, and the supply drop has 2 immortal keys instead of 4.
