I am using the restart script that came with the release.

IE- "cd $MOOHOME; ./restart TribalMOO"

Again, I am using the restart script which takes care of this.

It is just new objects. For instance, the player I created named zarko still
existed and had the same password, but the new object $irc was gone, as well as
the property on #0 to set that alias, as well as a couple other small verbs I
had added to $programmer and $player.

It does not seem to be creating these TrialMOO.db.new.#n# files. Should these
files continue to exist, or are they moved out once they are complete to
TrialMOO.db.new? If they are supposed to stick around then something is indeed
wrong. According to the log these files are written, but they do not seem to be
around at this time. The log entries from the date in question are in my
previous mail. I would have just sent a single mail, but it didn't occur to me
until I noticed a number of responses.

The following may be helpful:
