While testing the game through the 20081207 snapshot, I was told by the game to make a ticket when a sudden issue came up.

At SEEN6417 just before the passage(?) <0720> occurs, there appears three lines stating "No valid string, make a ticket about it". In the interest of being helpful, that is what I have done. I made a save file at this point; when loading it, usually REALLIVE freezes before anything can occur and sometimes it doesn't, so I guess it is a little fatal.
