TOPIC: Quest NPC's

Having problem with Quest NPC's ?
i had this too, when i E'd the NPC, i couldn't start it's mission.
Now i know how to solve it.
If you have this problem too, do this.
Go to Garry's Mod main menu,
Go to options.
Go to "Video" inside options menu
Change Resolution to =1280x720
this may freeze your game for a minute, but it's worth it.
(this worked for me, if you still have the problem, just mess around with the screen resolution in garry's mod options.)
Screenshots:
Before: (something like this)


After: (something like this)

It would only do this if you had the wrong resolution in the first place .-.
