(Note: haven't tested it in FUSS yet, so feel free to test it first)
After I used installarea to install an area, I typed areas. It still only showed limbo.are so decided to check and see what the problem was.
in build.c installarea function
* Sort the area into it's proper sort list. BUGFIX: Samson 4-15-03
sort_area( tarea, FALSE );
It might need this
sort_area_by_name( tarea );
Seems it doesn't like updating the list without it.
