that is just the worst way to use early access branching.
use it to give us access to the next upcoming "unstable" build (that is how every single early access dev does it, except you.....) not the previous version.....
They don't want to deal with saves, messed up by the old buggy code. They are doing us a favor by even providing that 2nd branch. Which I will personally skip because my saves got too buggy to continue with a few quest not doable, doggo going full pitbull on me, etc.
