Well, the reason you can't pick up items that've fallen in to the edges, or why you can do that little tactic Krezack does to avoid being shot sometimes (won't say, don't like it ;P) is because basically, it sorta doesn't register anymore (or something, someone back me up here ). So basically, with flags, the position sorta messes up when they touch the edges. SO I THINK what he's saying is changing the memory positions of the flags so it's in the right place or something...ask someone with a bit more knowledge about that. ;P
