I think I've found the bug:  FLAG_BERSERK was added and NUM_FLAGS
increased, but not all places that use NUM_FLAGS were updated!  One
place is get_ob_diff(), I don't know if there are others.  Please use
'grep' and examine _all_ places - that's the best method to prevent
such bugs (and to fix lots of other bugs as a side effect).

The effect in get_ob_diff() is that whenever an object's FLAG_ALIVE
differs from its archetype's FLAG_ALIVE and the object is written to a
temporary map file, an "Object 0" or "Object 1" line is written to the
file.  When such a map is read back the archetype's name is destroyed.
Easiest way to reproduce:  Cast a "build lighning wall".  But there
could also be maps that alter an objects FLAG_ALIVE.

      someone casts "poison fog":  however, "poison fog" is disabled.

      Maybe the failed search for this archetype sets up the heisenbug?

      Reviewing THIS code, I doubt it as well.
     
     
Looks harmless, even though it causes an annoying error message that
activates the debugger everytime the server is started.
