Well I extracted the default HUD and replaced the mod one with it, then installed the mod and my Green HP bar is back...unfortunately, the foggy water is back also. So I guess I can either have clear water OR an HP bar I can see...but not both, oh well.
Also, could either of you, OP or Plexasarus possibly tell me what program you use to edit the files? I would like to give it a try and see if I can modify the thunderstruck tree's to make them more visible like you did with the chests. :P Thanks.
Edit: nvm, my bad...the ocean is still clear under water, I tested it in a lake and it was cloudy, so the fog in the ocean is still gone :)
