## Description of the bug
According to laws of physics and chemistry, including real life as well, you cannot physically aim at a "fog". It is very bad, and no one wants to see people wasting rockets on something that's physically indestructible.

(Just kidding, but seriously, I dont think you should be able to aim at the fog, it doesn't have a use other than wasting a rocket and people laughing about it.)

## What's the difference with what should have happened?
You shouldn't be able to aim at "Dense Fog".

## How do we reproduce this bug?
1) Grab brute as comtech.
2) Target "Dense Fog" in LV-624
3) I don't know why but you can shoot the dense fog for nothing but money-down-the-drain funny.
