Hi, developer here!
Our lead artist had a few issues with the art side of things in the past few weeks. We're working out some details. We're working on a devlog for the new gen detailing a couple of things to inform of the actual issues.
We decided to send out emails to everyone who owns the old generator anyways, regardless of the upcoming update, since there is no reason to make you wait any longer. We sincerely apologize for the lack of communication.
