Sorry, posted in the wrong thread :-/ That's what happens when posting on mobile. 

Did you get a popup asking to crush the rebellion/bribe the rebels or do nothing? When someone respawns you should get a popup allowing you to keep some of the cities that you have previously conquered. If you didn't get a popup, then there was a bug, however, it would be very hard to figure out without a savegame.
No, when they respawn they either take Damascus without asking, or don't take at all. Well, I have a savegame which is some 40 years before they respawned, could it be useful?
Notre Dame and Leaning Tower (and maybe others) don't have a file in the arts/movies dir and ingame when I build them, it shows garbage (when it should show the anim or frozen pic).
Civs cannot trade techs before their "historical discovery date", this is to slow down tech progress.
AbsintheRed, to do what you suggested means that I have to keep track of when each tech was discovered. I will think about it, but it is considerably harder than the current scheme.
Yeah I know, this way we would have to keep track of each civ's tech progress. Or at least their latest tech discoveries in a few new variables
But it has it advantages, as I said in my last post
Having a hardcoded treshold for all the techs' trade dates feels very unnatural to me
I will try to solve the issue with the AI building large stacks of units and not moving to attack, this is a much bigger problem.
I will try to hack the tech dates next (with displaying the historic year and trading).
I found another bug, this time relative to technology:
Sometimes I research techs a bit ahead of their time, so that every turn the cost is reduced. However, in a few occasions, the cost is reduced to under the research points I have. So, it's like this:
Machinery
[...]
1 Turns (1705/1645)
And this extra research also doesn't overflow...
Could have been reported earlier: Upon discovery of Arabic knowledge you get a prompt to change to Trade economy, the describing text is corrupt.
Btw, why would you want to change civics when prompted? If you change at the civic screen you can change two civics at a time instead of just the one discovered.
