 The actual MiszaBots are neither functioning nor expected to become functional.
This may have several reasons, e.g. server configuration or server account problems, lack of following the changes of  Pywikibot version controlling, or the SVN vs. version.py battle (which recently killed my automated bot, too).

1) I guess that MiszaBot III was using archivebot.py (his name is in the list of contributors). Is that right?
2) does the statement above implies in some way that archivebot.py has flaws, which has been fixed by sigmabot III (the code in his/her page is different from archivebot.py)?
No, as detailed above.
