Rant: The flag name GRID annoys me. It should really be called OPEN.[/quote]
I agree. It took me an extra minute to realize what the grid flag did, because I am used to setting areas as OPEN or CLOSED, or in some code bases, there is a flag called HIDDEN, just like the flag used to make an object, mob or exit hidden, but it has the effect of the GRID flag when applied to an area. GRID isn't very intuitive, so I didn't automatically know what it meant the first time I saw it. No big deal really though, now that I know what it is.
