[Freeciv-Dev] (PR#19300) scenario saving

["Curtis Warren" <cwarren89@xxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=19300 >

Saving a game from within an unstarted scenario will not load again.
Try so results in an error along the lines of "no spe00000". They're
present in the savegame, but with an underscore after the second zero
("spe00_000"); removing these underscores gets it past this. After
doing this, trying to load it again results in a segfault.
