At the very start of the launch, we encountered an issue where the game build did not correctly transition from Early Access to the Full Release version. (This has been fixed, and the Full Release version is now available to play.)
We have also confirmed a problem where achievements are not unlocking, and we are currently working on an urgent fix.
