Over the past few days, there have been a number of occasions where the game freezes, and a buzzing sound comes from the speakers. This has happened a few times, but I have also had a number of hours of gameplay inbetween with no issues. I do play with one mod. I have attached my my most recent logfile, and the game save. The last occurrence was at around 15:18, interestingly, there was nothing much in the log at that time.
On all occasions, the game will finally respond, and I have been able to save and exit the game without any loss.
Cheers,
Chris.
