The event has occurred. It already happened. The save was made AFTER the event.
You can play on the English version, yes. Of course, on a modern version, without bugs, etc. But for the future, I recommend getting a Russian version.

Do you have enough money to buy 10 heroes? 25,000? What prevents you from buying a hero and then recruiting another one under him? Are there already 7 heroes, or are the rest filled in by companions? If the game offers dismissed heroes, you need to force it to offer someone else. This process is called "digging for a hero," and some players use a program for this that is not prohibited by one of our forum members - vbn.
A hero can be bought twice a day, provided that he attacks someone and flees/pays a ransom. After that, he can be bought, but he cannot be used. This includes not being able to take even one step out of the castle! This also includes not being able to turn to the hero at the castle to exchange troops!!!!
