First of all, thanks to everyone involved in creating the most recent patch!
1.04 installed over 1.03a. Started a new game as Southern Whites. Noticed a few minor bugs in the first few turns - Stalin's face taking the place of a ship icon (took a screenshot but lost it), and at one point I was unable to click on the orders tab with the tent icon until I restarted, but other than that, things were going great until around July 1919, when I starting getting CTDs during turn resolution. Here's the end of one of the logs:

Hope this is helpful. I cheated a couple times in this campaign by reloading the last turn, could that have corrupted the save game?
