Posts from Agraal does not spawn and causes a script error. Auto-translated

Game: Heroes of Might and Magic. Complete Gold Edition. In the campaign for the queen, in the mission: Sunset of the King (fifth mission). When freeing the queen, the following appears in the console: script error: Hero "Agrael" is not on map. Because of this, the map cannot be completed; Agrael does not attack, and the game becomes endless. Are there any ways to fix this?

Maybe this will help.
Otherwise, you need to study the scripts that run on the map in Notepad and emulate them. In the worst case, you'll have to enter @Win() in the console

Thanks for the tip, I managed to complete this mission, albeit with difficulty. However, the ogre still appeared on the map but remained stationary, so I had to attack it myself. The first thing I did was free Isabelle, and only then did I capture the castle.
