UNIT - Creature Balance + Visual Changes

I'm getting zombies raised from my nomadic centaurs. Is this happening only to me?

Apparently, yes. Because it says in the mod manual:
-The undead raising table has been changed. (The level of the raised undead is now equal to the level of the killed creature. More details at /topic/at/912459/)
I personally extracted a new raising table from the mod; I don't like it.
