If I try the latest commit of pywikibot's revertbot, I get this output:
>>> [[cs:Šablona:Experimenty3u]] <<< Sleeping for 8.6 seconds, 2016-01-23 19:19:51 Page [[Šablona:Experimenty3u]] saved Šablona:Experimenty3u: Robot revertoval stránku na revizi 13031013 uživatele Dvorapa z 2015-11-08T22:44:07Z
But nothing happens on the server. Contributions list shows only old contributions, Special:Recentchanges and page's history too and there is nothing reverted at all. Log output:
