Necromancer – “Ruler of Erathia” [Campaign 3, Mission 5]

Boris K - thanks for the help, now I understand. There probably isn't an auto-save feature because of the patch (heroes_might_magic_5_1.06_rus_cumulative.exe). What do you think? Should I use a different patch? Also, I'm playing the game on "RECRUIT" difficulty for the first time.
