Decided to get back into this, so updated the SVN to the latest revision and tried to setup the game again. Modules included: Greatest People (which still clashes with Bannor Chain Of Command), More Events, Frozen. Booting up, noticed these: Spoiler XML problems : Notice how I haven't got Bannor Chain Of Command installed and hence it shouldn't be needing to bother with the Chain Of Command or Master Sergeant promotions. Setup a Custom Game with many boxes ticked, 18 civs on huge Erebus Continent, and whilst loading the game got these errors: Spoiler : It looks quite similar to the "Python bug" discussed upthread, but it's coming up with C++ exceptions. Game then proceeded to not have a UI once the world had loaded, so exited and posted screencaps here instead.
