In tew 3 AI heroes are 'stand still', can't move. If it was one hero, killing all heroes from that faction, as I did consecutively would solve the bug, but I had to kill them ALL to get next turn. Berserker suggested there is a problem with AI calculating pathfinding.

Save (needs tew 3 mod.)

There is only one who can move in a restricted radius but only to recruit from dwellings. I completed the map 6-7 times with same settings and once I got frozen game. Those bugs occur also in SoD or Complete, some are identifiable, but a few are a mystery for me too.
