This happened while I played with Smarter Bandits <- is not needed for this to work btw.
Most of the time they stand off the roads, spying out for victims, and I like it, but they do this so halfhearted.
So I changed their standing and walking around to sneaking around.
Very simple, nothing special and should have no conflicts with anything.

-This will also effect bandits in camps. Good or not is up to you. I just let you know.
-They will stand up and run and fight normal if you're discovered.
-They will not sneak in interiors.

(Title is from my favorite song "Snake in the grass")
