when we install the jud6s mod, and then deinstall it, the graphical modifications (no water in flooded caves etc...) remain.

Would a character run with this glith still be recognized as legit?

I recommended to erase config.ini in case it would not, but we're still unsure about the fact that it would be invalidated or not...

Thanks for your answer

config.ini is authorized/recommended by the developers of the game: https://steamcommunity.com/app/250900/discussions/0/613941122558099449/

Think of it as in-game graphics options that they were too lazy to make an in-game menu option for.
