so. i have verified ever hvt and destroyed every buildling on the map marked in teal. my progress says i have 2 hvt's left and i just don't know how that's possible. anyone else have that problem? almost done with the game i only have 5 missions left.

Blanco and selano count as hvts.

I killed all hvt's and no achievement....

It says I'm missing four or five missions.  I even played both sides with the Allies/Chinese to maximize before the Battle for Caracas.  Side missions complete, HVTs complete, and target buildings complete.  The only thing left is spare parts (after final mission), but that's not going to fill the gap...

Buggy game.  In dire need of patch.
