Please explain your issue is in as much detail as possible.
After a steam update yesterday, my game just stops while I am playing it. It worked fine for a couple of hours after the update but then, a year after I was declared emperor of Brittania, it just started to arbitrarily quit in mid 1405. I was in the middle of a ware with Aragon and it seems to quit just after I win a siege. The timing isn't exact and its not always after the siege is over but so far its always AFTER I am named Emperor of Brittannia and in 1405. I was using some minor graphical mods but disabled them and its still occurring. I have tried starting from different saves and it still is happening. Let me know if you need more information.

Steps to reproduce the issue.
Not sure I can reproduce it exactly as it occurs at different times. 1405 is the only common thread.
I will upload the last save I had with all the mods off that failed, as well as the error log, dump file and any other logs that may apply.

Do you all ever acknowledge the bugs or help with investigating the issue? In the last week I have tried restarting from several old saves going back to 1403 and all are blowing up at some point in 1405. No one item seems to be triggering the bug that I can see. I tried to read the error reports but it doesn’t mean anything to me. I would like some feedback, even if it’s just “ yeah we looked and we don’t know what to do either.”
Thank you
