I really NEED a builder who can build (likle a constructionunit) other units, but he shall not be able to repair or reclaim.
I cant find a canrepair=0; tag or so
What can i do?

Edit: the canXXX=0; tags seems to not work for me anyway. I gave the unit the canguard=0; tag and it still can guard o.O.

Is the nanobeam hardcoded? I want to make a unit be built without the nanobeam - what can i do?

Thank you all!

Yeah, you're pretty much SOL on all regards there right now. Sorry
