BUG (?): I don't know if this has been stated, but when I play the "Quicklaunch 1.13 (Second Age)" (I think that was what it was, but I'm not positive), I can build all civ specific wonders, even when my civ shouldn't be able to. Playing as Gondor if that helps.
I've also run into a few blank CivP entries (links to blank entries, etc), but that's not a huge problem. I view the CivP as more of a novelty or luxury item, it's nice to have, but you can live without it.
I could give you more information, but I work 7 PM - 5 AM today, and then 3 PM - 9 PM tomorrow. On top of that we're moving on Sunday, so the soonest I could possibly get more information for you would be by Tuesday.

Playing as Gondor, and I've managed to establish quite the empire in a short span of time. Just found the Rohirrim, and that their empire already has more cities than I do
. That's easily changed though
