Does anyone else have the issue where no saves load after the deletion?
You need to delete the campaign file in the profile you are playing on (if you don't know, it's the name you entered when you first launched the game and that appears when you hover over something owned by the bots, like "Red Player, Blue Player," etc.). Go to Documents, then My Games\Heroes of Might and Magic V — Tribes of the East\Profiles\*your profile*\Saves, and delete the file with the EU extension. I also encountered this problem, found this file, deleted it, and everything started working.
The campaign is cool, although I would rework the archers into some kind of Elite Archers, so they also have crossbows and, well, I don't know, shoot slowing arrows or something like that. Otherwise, the archers seem weak compared to the red archers, and even 2 shots don't make up for it. In general, I have this question... Did you guys draw the unicorn for the topic header and the green knight's flag yourselves?) Or did you find it on Google?) I couldn't find it on Google, and I'm very curious where such a beautiful design came from

I can't upgrade troops to Unicorn Empire troops; there are no green troops at all.
Read the description in the topic header.
The campaign REQUIRES the NCF_Core and NCF_EU_Creatures mods to be installed! Without them, the campaign will not work past the first mission. If you already have them installed, you need to launch the game through "H5_Game.NCF.exe" (.exe may not be displayed for users who have not enabled the display of file extensions in the system settings), which is located in the bin folder.
