[My Health does not regen? :o]

Check your character details to see if it's caused by something. It's probably just a loss in your attributes (a flaw perhaps?)

[Character Skin tone bug]

I have run into the same issue. Specifically, it seems the game uses to Skin Tone 1 (the default one) regardless of choice. I have experimented with a few characters, it looks identical in game to paler skin tones. I have not tried darker skin tones.
