You're not alone. I'm having the same exact issues and I haven't even completed a single quest. I'm trying to beta test it but how am I supposed to do that when there are these major bugs that prevent you from even...testing.
Can Obsidian give us an update when they are going to patch this beta? I hope it's not another week till these "beta-breaking" bugs are fixed. I want to test the combat out, but that's impossible when my Wizard's grimoire dissapears at the beginning of the game and other stuff...
I guess I don't know for sure, but maybe they are running analytics and needed more testers to find the origin of the problems.
Who knows. But my point is have faith in the process. My understanding is the game has been feature-locked but it's far from done.
