I am looking for maps for Heroes III.

Hello! On the Heroesportal, there is a campaign about Sir Mullich
love, Sword and Velocity. The campaign description on the website states that the fourth map can be completed without completing the quest to kill Mutari, but in the version available for download from the website, it is impossible to complete the map without this quest.
Perhaps someone has (or knows where to download) that version of the campaign where this option is implemented?
