Spawning one invulnerable Unit! Please Help!

I'm having some trouble with a new map set. I'm essentially green in map creation, but Warchasers has proven a resourceful tool. I'm currently facing an issue where one of my spawners, usually the first one you hit when you start the map, sometimes two or three, will produce units without an issue with the exception of producing one unit that is Invulnerable. I've tried about a billion and six different solutions without trying to recreate the Integer A system of spawning from Warchasers (It just seems like overkill compared to a simple string of triggers you can just CnP and change locations/units spawned). If anyone has any insight into this issue, I'd REALLY appreciate some help. Also, and I'll be making a post in recruitment as well, My friend and I are seeking two designers/testers to help us complete our map set. We're working on a 90 lvl Gauntlet style campaign very similar to Warchasers. We're still Novice Creators, so patience will be required.


Thank You WC3C. What a wonderful community!

More details on your troubles would be nice, like:
1. What exactly is this "Warchasers" tool? (explanation, link, attachment)
2. Post code where you think the problem happens

@MasterofSickness I'd guess that he's referring to the Warchasers map from Blizzard

OnTopic: You'll need to provide more information on your problem. It would be a good idea to show us the trigger you're using. (right click on it -> copy as text, and paste it here in trigger tags) Additionally it would be good to tell us what units you're trying to spawn. (are they modified, if they are: does it work with unmodified units)
