Zepolak,
45°38'N-13°47'E, I can confirm Imperium bug.
And I've already proposed how it can be connected with espionage. When other civ changes to Imperium, you starting to get some negative income ( if this civ has stronger military than yours ). There is somewhere place in the code that sees this negative income and move science slider to compensate it. And probably there is another place, that set espionage slider to as ( 100 - science slider - commerce slider - culture slider ), so it changes espionage slider automatically. And probably there is a third place in code that calls every time espionage slider changes not by human, that set this "espionage weights".
This is just hypothesis - I just looked through the code not carefully, may be it is even more complicated.
When in current game I'll reach the stage of other civs imperium - I can send saves before and after, it is totally reproducible.
Also I can confirm Leonardo Workshop bug - after getting Leonardo Workshop my science increased in one game from 2k to 6k, some weird science amounts out of air appeared. I had Leonardo only once ( usually AI get it first ) so I can't say is it reproducible or intermittent.
And another bug with strange commerce points. This game I've placed in excel every single move all variables that games uses to calculate commerce and science amounts and rechecked the calculations. My goal was to find the first move when this bug will happen to find the root cause. And finally I get it - at move 204. I believe the reason is because at move 203 I've built CaravanSarai, but this is just the hypothesys.
This is the calculations.
For both moves 203 and 204 everything is identical ( even the same - 35 number of foreign connections ) , so science should be the same.
But I am getting 112.75 at move 203 and 93.75 at move 204.
Let's check calculations. I have:
34 coins from cells
27 coins from buildings ( 8 - palace, 5 - great lighthouse, 2 - wheelwright, 2 - candlemaker, 1 - apiary, and 9 - caravansarai ( 1 from base , and i have 35 foreign connections that gives 35/4 = 8 more ) )
+20% from Senate
This gives 61 * 1.20 = 73.20 coins.
Also bakers : 10 bakers from academy, 3 from School of Scribes, 1 from Myth of the Sea + 3 from Scientist = 17 bakers
Academy gives 25% on science production, slider at 100%.
That gives total bakers: ( (34 + 27) * 1.2 + 17 ) * 1.25 = 112.75.
Looking how game calculated it at move 203:
A little bit strange numbers in the middle, but final result is correct.
The same calculations at move 204:
Now final result incorrect too.
Numbers at Finance Advisor screen:
And at move 204:
So, 16 commerce lost somehow. Just a hypothesis: it is this "foreign trade" from Caravan Sarai. Instead of +8 it somehow changed to -8, and that gave this lost bakers. At least I can say that before building Caravan Sarai all calculations were correct.
Attaching two saves - before and after if somebody wants to look.
