Quick question on when magic sites generated

[Stavis_L]

1) If you're using a custom map (e.g. one created by SemiRand), some sites may be coded into the map, and will always be there.
2) Otherwise, and for the balance of the sites, they are generated when the game is initially created and stored in the game files (ftherland, I believe), so re-starting the game (other than by returning to a backup) will regenerate the sites.
