	That was a bold faced lie. The NAT discovery hashes are included in the 
the second and third payloads for aggressive mode. I think this was just 
a matter some initialization not happening early enough.

	I just now completed a bunch of cleanup for the phase1 and phase2 
handlers that was due after the all the churn related to the proposal 
auto negotiation work. The new processing layout should fix the issue 
you were seeing. I will test this to verify.
