Based on recent games, I had a desire to change something, namely:
a starting hero of level 5 appears with 3 stacks, surrounded by hiding places, money, and... a rest point.
I suggest that in such a situation, a save is made, the opponent is informed, and this hero is dismissed (broken down) into all 4 components, and the game continues. Upon subsequent appearances in the tavern, ignore him or buy him for troops and dismiss him.
You don't have to dismiss him; why be so radical? Just restart the map, and that's it.
