What sort of saved games are you referring to? Is this a local bug to 3dfibs or a problem on FIBS? If you type "show saved" at your command line you'll get a list of the games which FIBS itself considers unfinished.

There IS a small bug on FIBS which may lead to an incorrect game save - I, for example, have one saved game against "5" - who doesn't exist as a fibsplayer. Patti knows of this bug - it's not a real problem as the saved game will disappear in time.
