That's not supposed to happen. It is supposed to remember the parts so
it doesn't have to re-compute them.
Try changing
return if ($self->{PARTS});
to
return if (defined($self->{PARTS}));
on line 2705 of lonnavmaps.pm and see if that fixes it.

This isn't supposed to be necessary, so there isn't a way. If you want,
deleting the {PARTS} member of the resource object will reset the parts,
but that's only to let you continue developing while I/we fix the
problem; you should not normally do that and you need to take that out
before the end.

-X on the Apache call, but that is not related to this. The nav maps
routines do not make sub-calls within Apache, it is all done within one
child, as confirmed by the fact that nav maps still work when -X is used.
