Thanks for the help, I can't set it to human or else in the world editor it would look weird, I will try re-making the worker as a peasant. If not, I suppose I will have to redo all the buildings as human buildings. xD
ONE MORE QUESTION: How can I make Sentinal work on units instead of trees? i tried just unckecking tree and checking friendly, but the hero just plays his casting animation and nothing happens.
Edit: The reason why having the worker as human is bad for me is because I already have a complete race under human custom...Another thing, since it is a human unit it has the human build icon by default instead of the undead, and I'd rather not take the time each time I re-use this race to change the default to undead.
