I am playing the nation of Syzirzex and am about midway through the game. However, every time on the 23rd day of the 10th month, 1608, my game either freezes or crashes to desktop. I've verified game integrity and reinstalled the mod, but it doesn't work. I did give them a custom flag and unit graphics / colours, but even without them (same save but mod freshly reinstalled) it continues to crash on that exact date. Any idea what's going on?
