My bug list, big, not currently in reported bugs (I think).

[Black Rose]

* An intro movie that you cannot skip until after a long time. On the contrary to what some might say, it takes a lot less time if you manually switch off the intro movie, it really sucks up a lot of resources (manually edit file in civ5 folder).

* Not correct tile improvement display when selecting worker actions, sometimes wrong yield. Especially the case if a forest is to be chopped down.

* City state settlers that don't move away from a civ's borders, they stand immobile for the rest of the game if they can't settle down at the exact spot.
* Too long wait after attack, especially when range-attacking land units with a ship.
* Enemy not using settlers well, standing inside territory rather than settling down somewhere nearby.
* Great General couldn't pass an enemy scout, even while moving on my own roads.
* Research agreement: Greece declared war with me two turns after entering a research agreement, a benefit that should come after 90 turns (I play at marathon speed), which instantly gave us the benefit of a free tech. Is the AI exploiting a bug in the game?
* Diplo-message from the french between turns, and then the russians, saying the same thing: "I've noticed your relationship with Augustus Ceasar. While that's nice, it would be best that you leave their protection to us." Right after, the french took back its guarantee to protect a city state I was allied with. Now, is this a spelling error, where my own leader name appears instead of the city state I'm allied with?

* Memory/graphic bug? - Barbarian spearman unit sign without unit, passed through without any incident, but the sign remained at low red health bar. It was next to a rival city I had Open Borders agreement with.
* Memory/graphic issue? - One of the cows on a coastal tile was actually standing in the sea.

* Ocean tiles trapped between ice and land is called "lake" without "fresh water"
* Skip the "a" in "[City] will produce A [wonder] in XX turns".
* Peace treaties should be longer than 10 turns at long game speeds (marathon).
* Spending all ship movement, and then gaining an upgrade or promotion that gives the ship +1 move, will not wake the ship unit so that you can spend 1 more movement the same turn.
* Must you declare that you protect a city state EVERY turn? It doesn't remain in effect, and you cannot withdraw the protection like you see other civs do as a "public declaration".
* Gifted a unit to a city state, but it never arrived. It was a 1000 gold Legion, so it annoyed me very much.

The intromovie is as far as I know the game being loaded in the background of it.

* City state settlers that don't move away from a civ's borders, they stand immobile for the rest of the game if they can't settle down at the exact spot.

Wait... City state settlers?

* Ocean tiles trapped between ice and land is called "lake" without "fresh water"

I think that is because the Ice tile is rendered as a land that cannot be moved to edited in any way. I have seen it myself and wondered why it was that, but that what I could come up with.

* Skip the "a" in "[City] will produce A [wonder] in XX turns".

"The City will produce a Notre Dame in XX turns"? Since every Wonder is named it should be "The City will produce the Notre Dame in XX turns". That would also work with the Pyramids since the name is plural, however the wonder is singular, ei only one building.

Please provide a savegame where it is necessary.

All the other bugs are already known, sorry .
