CTD when clock hits 06 10 1690

[dualhammers]

So I looted a fat spanish merchant full of gold and was hauling it to La Grange to sell. It was June 03 when I entered the map screen. Everytime I let the clock tick to 06 it crashes when I am on the map screen. I tried going to open sea and back and that did not fix it. I tried reloading and that did not fix it. I tried sailing other directions and that did not fix it.

What do I do?
