Current questions and answers regarding the map editor.

Hello. And here I am again with my problems. The first one is related to mission 4 of my campaign. Judging by the feedback on the forum and walkthroughs on YouTube, the Necropolis castle is not destroyed. Although in the "Razed" section, it shows the ruins of a human city. Personally, everything works for me; the city explodes under "Meteor Shower" (screenshots are attached). I don't understand what causes this bug. The second problem: I don't understand how to systematize the appearance of "red heroes" in the tavern. Some players cannot hire heroes at all. Restarting the map solves the problem, but I would like to know: is it possible to eliminate this random probability?
