I haven't been able to figure out why it happens, but it did happen to me, and after searching and experimenting to figure out a solution, I did discover something: If you use the console to change the game hour to 24, it will bring you to the very beginning of the next day, and in the process, bypass whatever time the game crashes at without inducing a CTD. Since doing this, I haven't encountered this particular problem again, though admittedly, I haven't had much in-game time pass anyway, so who knows whether or not it'll happen again... Still, hopefully this helps others who are experiencing the same problem. EDIT: Full disclosure, though, I use LE, not SE. So, there's that... EDIT 2: I have encountered the problem again, and I was able to fix it again by using the same method I described before, but I also want to clarify that this solution will not work if timescale isn't set to 20.
