I am currently playing a game as Japan with 1.3a, and after I annexed China I noticed my resource supply was becoming very erratic. I had the computer controlling all convoy activity, and discovered that it had created in excess of 150 supply convoys all starting and ending in the same two provinces. Every other day it would switch ALL transports into these convoys. I switched off all computer control of the convoys and went about deleting all these supply convoys and reorganizing my existing ones, but every time I try to do so, the game crashes. Any one know what the problem is?
