I played only one game, yet not finished, since the june update, so it's too early to be sure about the flaws I noticed, but I'd like to know if other players came across the same things :
I was playing one difficulty below usual, (immortal instead of deity / demi-God),
but it seemed like the first time in 1500 hours that I'm leading in science from the very beginning. Is AI slower / less prone to build campuses? Maybe it's because I was playing against non-science civs? (England, India, Mali, Spain, Rome) or maybe because I'm used to play on Large maps?
The second bad thing I noticed is that the AI was much slower to build walls. There still was almost none around t200! (epic speed) which seems really late compared to my previous games. Too bad I was playing as Canada and didn't want to go to war.
The new diplomatic system is better, but it's really lacking of options to see / influence / guess what the AI will vote.
Totally unrelated, but Im really struggling to use mods, even the updated ones. I often can't load anymore my games, 3 files are always missing when I verify the integrity on steam, my logs report Text/localization problems, and when I disable all mods, delete cache, mods.sql, etc,.. and I still can't load the game
Only solution I found is to delete every files on the 3 data folders, disable the two expansions, re-verify,... Anyone coming in those kind of issues?
