I was playing on the ring world, prince level, with raging barbarians. 
Spain had been a bad seed from the start.  Even getting city deep into “my”
blob of land and doing a influence bomb on me.  I was a little ahead of her
in tech.  So she declares war on me and attacks with the large built up army
the AI always has.  She attacked with Inf,, Cav,  Fighters and Cannon.  I
have Tanks, Gunships, Mech Inf., Fighters and Bombers.  She sends about 40
units at my nearest city and just barely takes it, killing my two city
defense specialty mech inf. guarding it. (I really like the new promotions
and how you can specialize your troops.”

We both go to a total war footing and I have a good ally that does a major
anphib invasion and between us we capture 6 of her cities over the next 20
turns.  She has gotten gunships and tanks during the war.  I have sunk her
fleets and have pretty much wiped out her standing army, During the war I
got composites so have a stream of Modern Armor flying out of my 20 cities
at her.  She begs me for peace and I am not feeling kindly.  The turn after
she sues for peace and I turn her down to my surprise 22 GUNSHIPS MATRILIZE
IN THE CENTER OF MY CONTINENT, WIPING OUT ALL MY S-S-BOMBERS, JET FIGHTERS
AND WORKERS. 10 MODERN ARMOR AND 8 ARTIES ATTACK THE FORWARD CITY.  8 BB, 8
DD AND SWARMS OF BOMBERS WIPE OUT MY FLEET!  That's right, she jumped up 3-4
tech levels and hit me with more units than she had cities in one turn!

Has anyone else seen behavior like this in a game?
