Hello all , who can help me with something .
The Question: I want to make the trees invisible . I ask becouse it happent to me 1 day ago and now i see it again .

Are they entities or are they world props in the map?

I played on Evocity ween happent this.

In the server console put

[lua]for k,v in pairs(ents.GetAll()) do print(v:GetClass(),v:GetModel()) end[/lua]

Copy the console log, to facepunch.
