Did you install patch "f"? Because...
No, I hadn't. I guess it's released now; I can't check to see if it fixed the bug I had because it breaks savegames, alas.
System Issues:
1. "GFC error: failed to initialaize the primary control theme" error loading the mod. You will recieve this error if FfH isn't installed in the correct location (under Program Files\Firaxis Games\Sid Meier's Civilization 4\Beyond the Sword\Mods). If you don't have Civ4 installed to that location just make sure the FfH is installed in the same directory as Final Frontier, Age of Ice and the other mods that came with BtS. Also make sure you have installed the full mod and not just the patch.
the first post in this thread is a good read
Why if Herne the only Centaur that can't get defensive bonuses?
