Arvantis, are you sure you had finished construction of it?
If you hadn't finished construction of it, my understanding of what's supposed to happen is that it gets removed from the build queue, you probably get a brief message about how you can no longer build it, and the hammers put into it are actually stored but not visible to you. If you finish another monument, it should be able to be constructed again, and it should have the hammers you put in it from earlier.
If the above does not resolve the problem, can you please upload a gamesave and instructions on how to reproduce in the bug reports forum?
Yeah, I already had finished base buildings in my cities (like, library, barracks and monuments).
I wonder if i will find a certain savegame.
If not, I will check it again in a new game.
Theoretically, I should be able to build a national epic in my first 2 cities very early as soon as I have the required tech (Philosophy AFAIK).
Especially the national epic is a wonder which must be build very early to get the most of it.
I will double check if again in a new game and report it in the bug reports forum, aye.
Another pair of questions:
1.) What happens to archery promotions if you upgrade them to riflemen?
Are they lost or transferred into the melee twin (shock or drill)?
2.) How is the city strength vs. enemy units calculated?
By city size?
And how must i qualify the city's defense strength if encounted by enemy units?
This question buggers me cause i wanna know if castles, city walls and Kreml are totally worth it (and, if certain SPs stack with the city defense - like oligarchy, GGs etc).
3.) Any hint how to "foresee" the strategic ressources i need in the lategame (Oil, Coal, Alu)?
My problem is: i tend to build small empires relying on a mediocre culture border.
If i have no luck that my CS will give me the needed strat. ressource, I am forced to build a new city where oil, alu etc pop up.
I'm wondering if i can do something in the first place (settler phase) to secure late game those ressources.
I don't rely on other civs to trade oil etc since this is too uncertain if war breaks out (=> 50% penalty on units relying on those strat. ressources hurts).
I know that it is not THAT bad to have some desert or tundra nearby since there is a chance of success that oil will pop up on such tiles.
What about the game setup called "strategic balanced ressouces"? Does that increase the chance for my small empire to get strat. ressources lategame?
(I know that question #3 is a bit long but i was hestitating to open a new thread for that one - sorry

).
