Just let's gather some useful information for Modders, what got broken, what didn't etc.
1. Beth has removed the hidden plugin selection, refer https://www.youtube.com/watch?v=UNx6f5v9TxM to fix this, basically you want to do what needed to be done before the hidden plugin selection was found
2. There is still absolutely no love for leftys and arrow key players, I still can't conveniently use the settlement building workshop with arrow keys, followers will still occasionally run into my forward moving keys and activating dialogue etc.
3. In order to fix the problem you eventually get when you attained to the Beta patches, turn them off, then verifie game cache in Steam, after you removed the plugin.txt...recreating your .ini's might by recommended as well
That's the three things I had to do to restore anything like I was used to yesterday.
Thank you very much for the fixes Bethesda, unfortunately I don't got anything else from it then hassle. Fix the darn keys!
