I was fiddling with the expanded.txt file, so that the Byzantines had an extra level for armour, doesn't really matter in this situation, but the aftermath matters. After modifying the expanded.txt file, it just crashes whenever I try to play grand campaign, and it leaves me with this stupid background music that really annoys me, giving this circumstance being the aftermath.
And I tried to replace the expanded.txt file with the one from my backup folder, no hope!
Any help would be appreciated!
