I have added help and strategy text for intihuatana. I'll do civilopedia entry later.
In your amendment to the intihuatana lua you added a lua notification for if an intihuatana is built after Scientific Revolution has already been adopted. I don't think this is necessary. The player will already be aware of the upgrade and the building is not substantially changed, unlike with the Kabuki. I think it is fair to silence this notification; it's just clutter.
For an example, consider if the game notified you every time you built a castle after having constructed Neuschwanstein, or adopted the Nobility policy.
Updates that should be added before publishing:
- Horse archer unique promotion lua has not been incorporated into the civ5proj file, so it has never been tested. The dummy promotion is already on the unit, but doesn't do anything right now
- The Tarkhan heal on pillage lua seems like it should be a quick fix. It should be very doable to get that working before v 28 is live. With those 2 fixes, Huns will be complete.
Updates that we will probably save for v29.
- Portugal - none of the lua is working as intended for this civ.
@Blue Ghost - I Guess Zulu and Huns are finished now, right? Does anything more need to be done w.r.t. the alti cur tribute?
Tentatively, I would say you can mark Huns and Zulu as Code complete, but I would edit Portugal as "in progress"
