The same thing happened on ForestMOO when #2 was hard recycled and I had to
fix it (I didn't have server access).  Once I realized what had happened, I
figured I'd just have to renumber(create($wiz)) to get #2 back, and then set
it's player, programmer, and wizard bits, but this didn't seem to help all
the tracebacks.  I eventually figured out the problem was because all of the
verbs been chowned to #-1.  I'm not sure exactly how this happened, or if
it happened to the properties (I fixed them along with the verbs, but I
don't check if any of them were actually screwed up), but I didn't think
much of it at the time.  Maybe it only happens when things with their player
bit still set are recycled?
(and no, I won't mention how #2 was recycled, but it wasn't my fault ;)
