In the final mission to defeat Ajax (with help from your awesome clone), I talked to him, destroyed the 4 destructable objects (in order they came up on my HUD Nav), but Ajax still retained his beefyness and was un-killable.
I left, set another mission to restart the Ajax mission and went in to redo and it went fine, just posting this as a heads up and for others having the same issue not knowing what to do.
