Thanks for these. In order to continue your game, you'll first need to delete your Trebuchet in Gergovia. You're about to lose that city to a civil war and for some reason the game crashes when the Trebuchet there is converted to the rebel civilization. Still trying to figure out why so I can fix it for 1.23.1.
Secondly, by unfortunate coincidence there is also an AI Endless Tun bug (a flaw in BTS itself) on the same turn. Normally I'd just get you to hit Ctrl-C (CMD-C on OS X) to escape from it, but I accidentally broke that keybinding in 1.23. So you'll need to enter worldbuilder and delete the Anasazi Pirate at 30, 39.
Thanks so much! All of your suggestions worked!
Also, I've played a little further on and researched humanities but when I reform with a great prphet I am not able to adopt humanism as a tenant? Is this wad?
