I could only find vague information on the promotion in the Civopedia, but I did learn that it requires 'Grave's Placeholder' which in turn requires 'Future Tech'. Is this a bug? How did the Aztecs get this promotion and what are it's effects?
No, this in not a bug. Blessed in and of itself does nothing. All it's there for is to gain access to the two other Religious promotions (Spiritual Peace and Martyr). The "Placeholder" tech is there so I can add things to the game that I don't want you to directly have access to. For example, if I didn't have the "Placeholder" then anybody could gain access to the Free Promotion and Blessed promotions in the game, whether or not they build an Armory or had the Spiritual Trait. Does that make sense?
Secondly, I have access to three oil sources, two on land and one on my coast with a drilling platform. All sources are improved and connected to my cities, yet none of my cities have access to oil as a resource. I messed about with the world builder a bit to test it and even gave myself every tech in the game just to see if there was something I was missing.
It seems however that I just cannot have access to oil in any way whatsoever even if I have the resource tiles properly tapped. A game destroying problem to say the least, because it means I can never build Modern Era weapons.
Can you post up a savegame that has this problem in it?
And lastly, I wanted to know if there is a way to remove the Victory alert that is pasted all over the screen after someone meets certain victory conditions. On the last game I played, the Inca won a cultural victory in 1348 AD while people were still just starting the Industrial era. Naturally I wanted to carry on playing the game but the huge white 'PACAL II WINS CULTURAL VICTORY!!!' font pasted all over the screen is annoying at best.
LOL... I'm not sure what I can do about that. That's part of the vanilla game. Maybe uncheck the Cultural Victory when making a custom game?
