Hmm, Detailed Worlds appears in many of these crashes....
You can kind of remove mods from a save file. Open up the relevant .modinfo and comments out using <!-- --> everything after settings (but leaving the final </Mod>). Not recommended for anything but debugging of course.
Thanks for this tidbit of info, I too did some testing with this method.
1. First I commented out the Detailed Worlds .modinfo, still had the same issue crashing during the Aztec turn.
2. Then I reset the Detailed Worlds .modinfo back to its prior state.
3. I commented out the 8 Ages of Pace .modinfo and the game progressed through to the next turn, no crashes. (I did not play the next turn)
4. Reset the 8 Ages of Pace .modinfo file and got the same crash to desktop.
The one behavior I did see is that one of the Aztec cities did grow from size 15 to 16, but that was just an observation. (This does not matter, see below)
I will see if I can narrow down the file which may have the issue, not sure how that will go if I can even comment out individual files or not.
Thanks again for all of the help! (Another game I started seems to be working dandy so far with the same 2 mods)
Edit: Narrowed it down to the FasterRoads.xml file, in particular the ROUTE_INDUSTRIAL_ROAD.
When I comment out this section it worked and progressed to the next turn.
After messing around with a bunch of other settings for this XML tag, I think it may be the MovementCost, I do not think the game itself (not the mod) can correctly figure out the movement in some cases. I updated this value to a bunch of other values (.38, .4, .5). When I set it to .5 it did work.
Either way, I believe it to be a Firaxis issue and not the mod. Hope some of this helps!
