Warning and workaround for bug that deletes the savegame.

[Janneke]

There is a really annoying bug in this game. If you start the game, but immediately close it without actually playing, your savegame will be deleted!!!
To avoid this bug, ALWAYS resume your game after running it. Just one second is enough to avoid losing your progress after quitting.
I'm afraid people will read this message when the savegame is already lost, but I hope some will be warned in time.
