Take fall damage when vanished

hi
as the title says you take damage if you unclip and fall to the ground whilst vanished

same problem and i cant cross rivers or swim

i can kill players whilst vanished

My mod does not have access to no-clip.  He only can vanish.  When he accidentally falls, he does take damage and has needed help getting up.  My other mods do not recall this being an issue in the past.  I cannot confirm as owner of the server, I had no-clip activated at the same time.  If you need further details, please let me know and I can provide them.
