Buildings Won't Build!?!

I'm making a TD (oh no not _another_ td) and my buildings wont build.
The builder will start the building, but the building will not continue to build.
It stays at its initial hp. The sound and status are of buildings. You can even cancel the build. I have noo idea why this is happening. I gave my builder repair, then repair (human), then none, then both, yet still it doesnt work. Could it have anything to do with my builder being a flying unit?

Any help would be greatly appreciated.

I've seen this issue before in many maps. Personally I've never encountered it myself however.

Is this only for a single building, or all? If so try giving the builder a default tower such as Scout Tower and see if it builds correctly. I have a feeling this is a problem with the towers, not with the builder unit itself. I could be wrong however, like I said, I've never had this issue myself.

I had this trouble a couple of days ago on my map, did all kinds of things to make it work, think the change that actually help was to change his unit type to Worker.

oh... I thought it was another case of the unit not having the ability repair (human) thus not being able to finish the building construction.

What race is the worker? What race is the building?

Is the building a structure?

What classifications and what abilities does the worker have?
