Posts from Problems with the “The Unusual Betrayal” campaign. Auto-translated

I'm having some problems with the "The Unusual Betrayal" scenario (scenario 5) in the Haven campaign, where I need to defeat Sir Landrew. I've already captured all the towns, mines, and buildings. I've explored every possible corner, but the scenario won't end. The task is to destroy Sir Landrew. I know he's blue – I captured a blue castle – but there was no Sir Landrew on the territory of the blue faction. If anyone has encountered this problem or knows how to solve it, please help!

Some problems with the Order campaign scenario 5 "The Unusual Betrayal" where you need to Defeat Sir Landrew. I have already captured all cities, all mines, and all buildings. I've searched every possible corner, but the scenario just won't end. According to the objective, I need to destroy Sir Landrew. I know he is blue—I captured the blue Castle, but there was no Sir Landrew on the blue territory. If anyone has encountered this problem or knows how to solve it, please help!

Dear A-leksey, if you want to receive help, first format this thread in accordance with the section rules...
And one more piece of advice—it's better to try using the search first; most likely, this campaign has already been discussed!!! ;) (unfortunately, I'm not an expert on 5, so I can't say for sure)

I always start by searching and have looked not only here. If I can't find it, then I ask people for help. And the question is not about Heroes of Might and Magic V, but about Heroes of Might and Magic IV.

I've encountered this problem before...
but I don't remember where he wanders around anymore... I've played through the campaigns several times, and now I just don't bother leveling up this traitor anymore. :
I think he came to me and attacked (I'm not sure, it was a long time ago).
