I got stuck inder water, i had the violation message thing, I used antihack.terrain_protection 0 but now when i get into when i try to use the vanish comamnd from the plugin my character wont  lift off fro mthe ground, it shwos im in vanish mode but i still act as if im a player walking o nthe ground

Check your config/Vanish.json it should have:

"NoClip on Vanish (runs noclip command)": true,​

or when in vanish hit F1 and type noclip and hit enter

for some reason it rmeoved me from the user.cfg,  i had to grant my self back as owner and re write the cfg and it works
