When I loaded the game again..
Every turn, they'd jump down to a 'normal' score.. and the big number would multiply even further.
.. Now this wouldn't be so bad.. but , it effected politics and .. The enemy was super stupid even. On insane all he did was send scouts and Pioneers after me because of their hps.

.. Reminds me. I had Pioneers (solo) do 33 damage to a guy.. How the hell does a pioneer damage someone?
