Wierd Problem

Well this is not a trigger problem but here we go.

I am trying to let a peasant be able to build ancient protector, but what always happens is he can place it but then he cant continue building it. I know this could be a problem because of the night elf building loop, but I want to make it so that he can be building the ancient protector "outside of the building" unlike orc and night elf but like human and undead. So please, any help?

I got the same problem some time ago, I have found a solution, the builder and the building has to be the same race, just change the ancient protector to Human, it worked for me.

If what he said didn't work, make sure the peasant has the repair ability. Once it starts building, it uses repair to finish it. Blizzard just did that so you can fast build with multiple guys.
