Very nice map. Really enjoying playing as England (thanks to the fact that their starting location is actually viable!). Currently up to turn 234.
I've noticed two issues, however. The first and most important is that it crashes often once you get passed the early game . I know others have reported this. My crashes are persistent, but do not happen at a specific turn. In other words, if I reload after a crash I can usually continue playing, but the game will likely crash anywhere between 3-10 turns later. This is obviously quite annoying, especially because it takes so long to load a huge map on my computer . Not sure how you can debug this.
The second issue is that some countries occasionally get the wrong icon in the notifications involving war/peace declarations. For example, the tooltip would show that the Arabs declared war on Songhai, but it would have the icon for Egypt instead of the Arabs' icon. Still, it's a minor issue compared to the crashes .
