I'm doing it as you said, but for some reason, it's not in the list for downloading modifications. Only other ones are available((

I understand about the issue with the Castle. I have that one.
Regarding the bug - if you capture the human capital, the road to your Castle is blocked afterward; you can't even get to the portal to the Castle. I can send you a save file if you want.
Well, I probably intended it that way. I don't remember why) Summoning creatures is available.
Download the file, unzip it twice. The weight of the unzipped file should be approximately 73 MB. Then, put it in the game folder, in the same place where the Maps folder is, but only in the UserCampaigns folder. Load the game, Single Player -> Modifications -> Load -> The Beginning of the End. Load it. Play)
