First of all thank you so much for this mod. I love Civ, but I way prefer ancient and medieval eras (and fantasy) so this is perfect for me, especially as there is no Fall From Heaven 3 (and FFH2 crashed a lot for me in Civ IV). Over the last few days I have been playing the latest version of Anno Domini and I have been having similar stability issues to Kyklon. My crashes have been happening when I am playing on Online speed and mostly seem to happen around turns 50-70 when I am with Bodvoc. They happen in single and multiplayer. I tried disabling all the leader packs with Steam Workshop dependencies to see if it would help, but no luck.
I can link some save files soon if it happens again and if that (or anything else) would help let me know. I have tried about 5 games as Bodvoc and it happened 4 out of 5 times (at turn 110 I abandoned the game that it did not crash because I had played myself into a corner). I was able to complete a game that went way past 100 turns as Ajatasattu (maybe Bodvoc is somehow the problem). In all the games I played the AI usually randomed the female Celtic leaders if that makes any difference.
PS I just tried to play Tomyris 5 times and each attempt did not show the proper loading screen. I have attached screenshots. It shows the loading, then when you get to start game you have to press escape to get off that page. Once you have pressed escape it throws you into an AI only game starting at turn 40 with Carthage as the only civ and a bunch of city states all automatically moving through turns at a pace of about 1 turn every few seconds. I had to attach an autosave of this because when you go to the menu and click the save game button nothing happens.
