New here? I'm Roha — want a quick tour?
Each time you capture 2 castles, a red hero will appear. He simply heads towards one of your cities, each time a different one.
You'll laugh, but you'll have to redo this mission. When installing patches, you have to restart the last mission you completed, otherwise, you'll simply be kicked out of the game or experience what you just described. If you really can't be bothered to do it all over again: uninstall the patches back to the version you used when completing this mission. Complete it, reinstall the patches, and you'll be happy!;)
I replayed it, defeated three red creatures, leveled up my heroes to 25-26, captured all the castles, and was congratulated on completing the mission, after which I ended up in the main menu. This was all done after purchasing the Russian version and applying patches up to version 1.3. I selected "start the mission again," replayed it, and the result was the same. Please share a save file at 1(dog)mgr.ru. I have no desire or ability to start the game over again.
in the city, when you build the magic tower to at least level 3
