Questions about the Heroes 4 map editor.

Let me put it this way, a hero will definitely not appear in the house of seekers. Does the option I suggested work? Regarding the 5th-level scout, you can disable this skill altogether in the map settings. You can lose a hero in a losing battle in treasure rooms, for example, in the Minotaur's Labyrinth or the Dragon City, or in any location where you receive gold and artifacts for winning. But that's just some extra information. My advice is to modify your scenario and make it simpler in terms of scripts.
