I remember a while back having to set an antihack violation command to 3 to prevent players from being pushed through walls by doors. I can't remember the command and was wondering if anyone knew it off hand?
Doors pushing players through walls
I think this has been fixed anyway. The only way to glitch through walls now is if the server does not wipe teleport/home data and you TP to a coordinate in the new map which is below the map.
As i remember it happens when you changed antihack settings + possible on FauxClip plugins
