CT builders only.
Type CT SAVE or SAVEZONE to save your clantown, committing any changes you
have made to rooms and mobs to disk. Doing this will avoid any work being
lost if the game crashes or resets before your town can save automatically.
Type LISTZONE M (m for modified) to see if your town needs saving. This
display lists only zones that have not yet been written to disk.
