Well it appears I fixed it. AIBuildThis=yes was somehow commented out on the Construction Yard entry. That creates problems. Yay! 
The plus side of all the debugging that I did is that I found and fixed 2 other IEs. It just took a little more thinking. Thanks everyone for letting me post my dilemma here. Work on AR2 continues.
So someone should add to the guide for the AIBuildThis= tag, that a Construction Yard MUST have this set to Yes, else you get a crash at the beginning of the game when the AI plays as that side.
