As far as I know the patch only affects BTS, but not Warlords. Regarding the Firaxis Download page for Warlords, 2.13 is still the last version. The Warlords-Pitboss games I play in had no problems with the new BTS version, so I assume that Warlords did not get patched.
To verify this you should check the warlords folder after having applied the patch. The readme.htm should give valueable information about a version change. I cannot do this since I don't own BTS.
@mildge: plz resent the turn, I could not open because it was the wrong savegame.
