Once again, my tools don't work on the world.

[escher]

Just like the other day, my tools will only work on props, not on the world. I don't know what caused it, but can I please get some help? I don't know what changed. If you need to know something, I can probably tell you.

is this on single player or what?

Also have you got prop protection?

Have you downloaded [url=http://www.garrysmod.org/downloads/?a=view&id=68239]This addon?[/url]
It stops you from using the toolgun on the world.
