Invisible walls

Hello,

So in my dedicated server, in most if not all the maps, there is an invisble wall that follows all my players. So, if a player tries to attack another player, or tries to see their name, they cant. If they try to attack, it ricochets off something right in front of them. If they try to activate something, is doesn’t always let them.

Hitting this invisible wall with a crowbar emits a gravel/dirt particle.

Shooting it sends sparks flying everywhere.

PLEASE HELP! It’s really annoying and disrupts gameplay.

I’m running TTT with most of the weapons overwritten with M9K’s weapons.

there doesn’t appear to be any LUA errors popping up.
