Okay, what's wrong here? (Fatal Error at map startup)

Well, I'm making a map, but right now there's a little problem. Everytime I start up the map, like a lot of the cases here, it gets to about 75%, then crashes with a Fatal Error. Anyway, how is this being caused? I have no triggers yet, but I do have a few buildings that I think might be the cause.

There's one building, a bush, that you have to kill to proceed. Now, I changed around some of the pathing for it, namely these ones:

Art - Ground Texture: Ancient Protector, Corrupted Ancient Protector
Art - Shadow Texture (Building): Farm
Pathing - Pathing Map: Arcane Tower, Cannon Tower, Guard Tower...
Pathing - Placement Requires: None

The building is based off an Ancient Protector. Can anyone see a problem in there? Or is there a bigger problem I'm missing?

Edit: Okay, I've figured a few things out. I fixed the pathing, gave it a movement speed, made it only buildable on places you coul dnormally build on (instead of everywhere), and gave the units to Player 12, instead of Neutral Hostile... but even with all this, it crashes at about 85% now. What could I possibly be missing?

This is the problem ;)
What is wrong with there??
Dun make it to NONE.. Reset it and the problem is solve!
But if you want a pathing none building, use shimering portal @ human campaign/speacial...

Hope i helped you

Edit: Thanks for the help, but I tried what you said and it still crashed. But I found out what I did wrong. Oddly enough, I think it was because I had them based on ancients, but they only had the Root ability, so then I added the eat tree ability and it worked... =/
