Game freezes by turning from Summer 1719 to Winter of 1719 (that should be turn 39 to 40) by playing with the Maratha fraction. I've finished the Grande Campaign with the French and Great Britian thus and it did not freeze.
The freeze occurs when it's the turn of the Iroquis Confederacy. I tried it a couple of times and it always freezes at that point.
The mod is amazing! Thanks for this great mod and hopefully you can fix that crash. I love playing as the Maratha Confederacy, so it would be pretty awesome if the game wouldn't crash :-)
Continue your good work!
