The test version is full of bugs, it is still incomplete, of course, there are many new things (Bath). I recommend waiting for the release for Patreon; The experience will be much better. And no, we don't have the alpha version. It was distributed to a few and does not seem to be an advantage, just a consideration for those who support it. If not, you don't lose anything, just wait a little and a polished version will arrive for you.
