I think I saw someone mention in the thread that their mission wouldn't end. I think such a save could be counted, but only if all the map's conditions are met, namely:
1. The border has been crossed.
2. ALL fortresses have been captured.
3. All enemy heroes have been destroyed.
4. The monks in the circle have been destroyed.
It should be easy for the judge to check if these conditions are met and see what day it is. Is that how it works?
