I just uploaded a version where the start.ini option will disable even more of the threading
cncLevel = 0
Try that to see if it helps. I don't know why, but for some reason maybe your processor is crossing bounds that other processors don't. I have tested both Intel and AMD processors that I have, and the thread blocking mechanisms appear to do the proper job to prevent threading problems, but since the only updates I have made in this area deal with threading, I made that cncLevel option disable some of the recent changes, so it will act like the old way. Of course this will also revert it back to what the original game did for all this logic and make it single threaded in these areas, but that is how it was always done before anyway.
