I was reviewing the official mods with Enchanted Editor, and I noticed in some of them,( Area Effect Arrows, Bitter Coast sounds, Helm of Tohan, Entertainers, and Master Index), there are 12 GMSTs listed as being altered. After looking at them, I felt suspicious. It was a long time ago, but I seem to remember these 12 as being needless changes, or possibly bad. I was going to delete the GMST changes, since it's the same 12 in all 5 mods, but wanted to check in here with the community to see if that would be a mistake first. Here are the 12 game settings.

fDifficultyMult
fNPCHealthBarFade
fNPCHealthBarTime
s3dHardware
s3dSoftware
sAuto_Run
sCreateClassMenuWarning
sDifficulty
sEasy
sHard
sMaximumSaveGameMessage
sSaveGameNoMemory

Thank you for taking the time to read this.

Yep, you can (and should) safely delete them. Even the game developers make mistakes. :^)

Thank you.
