NCF – Extended list of Neutral creatures.

I have a question. I'm creating dwellings for NCF. I've created several based on building models from the Combat_Arena editor objects. The last one I made for the NCF Night Elf Archer, based on MapObjects\Grass\Combat_Arena\Rampart_sidetower. In short, it's an Elven tower. Now I'm digging into the settings. Can someone who knows help me? Is it possible to place a Night Elf Archer on this tower as a decoration? Like during a siege, when an archer stands on top and shoots at enemies. I tried to make it an effect, but unfortunately, it wasn't successful.

Tell me, why doesn't the game react to this mod, and not just this one, but to all mods that use file names like Creature_***?
Could it be because I have the version from Bukka?
Although I'm not sure about this, the game folder is named Nival Interactive instead of Ubisoft.
