"Necropolis" - changes to creatures of levels 6-7.

As an option. I'm still puzzled about where I made a mistake.

After all, we didn't change the link in the .exe file itself, but only one screenshot. Therefore, if we hadn't guessed the path, everything would have remained as before. But here, the screenshot has changed, which means the path is correct, and the problem lies in the screenshot itself.
But I can't figure out what the problem is. Two identical screenshots, only instead of one, there's a black knight (it works perfectly), and instead of the second, there's a death knight. So, the names are correct. What could be the problem? There are no differences in the .xdb files, except for the link to the dest name, which is correct.
