so, i read the patch notes and got excited by a lot of it. i just loaded up a deity Korea standard game and this happens:
Met Japan on turn 9. Sold him my first lux (Copper) around t30. He asks for DoF. on t32. Sold an embassy to Catherine on same turn. Japan denounces me on t33. Then he asks for straight up embassy trade on 34. How does any of that make sense? Later on Ottomans dow'd me and Japan dow'd Ottomans on unrelated turns. I joined the battle and used my CBowman to attack his nearest city but a barbarian was in the way. I cleared the barb so I could keep attacking. Japan denounced me right after it. What?! He was at war with Ottomans as well.
By turn 90 Japan and Greece DoWd me. Both of them were at war with Ottomans. Greece did it because I settled "near" him (10 tiles from his nearest city). At first he asks me not to settle on lands he deemed his own. I agreed and settled my 3rd city further away, about 15 tiles from his nearest city. He said my word was worthless and denounced me.
In Greece's list of reasons it had 1) He coveted lands I own 2) had become friends with people he was at war with and 3) Was friendly with someone they had denounced. The only problem with that was I became Friends with Catherine before they were at war with Greece, and France, who i didnt have a DoF with but was friendly, was denounced by Greece after I became friendly with France.
I'm really hoping a lot of things really were fixed but AI diplo doesnt make as much sense as I thought it would. I was playing Korea because I didnt see any mention of fixing the Hwacha bug so I thought Id test that out. I rage quit when Japan and Greece joint dow'd me and took 2 of my cities in 4 turns. I'm going to give it another try and see what happens, but I was a bit too excited to think it was "great" now. Im sure the other conveniences will be really nice but this patch is quite large in what they fixed. It will take a while to see many of the fixes in action.
