Please explain your issue is in as much detail as possible.
Attached save was started in 3.0. Worked fine with the current 3.0.1.1 beta, thats why I played with it in 3.0.1.1 during the last couple of days.
Played today for some hours, game saved and loaded a couple of times normally. After a short lunch break I started ck2 again and loaded the save again -> Now if I try to progress to the next day it crashs to desktop.

Seems to be the same issue as reported here https://forum.paradoxplaza.com/foru...oading-save-date-change-causes-crash.1140702/ and here https://forum.paradoxplaza.com/forum/index.php?threads/ck-ii-errors-in-error-log-with-crash.1139475/

I added the .dmp if it helps. error.log only has missing buildings stuff as reported in the threads above, don't think thats related to the crash. The other logs seem to have no helpful information. (I can upload them too if wanted.)

Steps to reproduce the issue.
Load attached save, progress to the next day. -> It will crash.

Now I feel dump. I tried different changes (killing characters, changeing titles, etc.) for almost 2 hours until I decided to try to attack someone before progressing the save. -> That 'fixed' the issue.
So only way to further use the attached save is to immediatly declare war on anyone and only in that case it stops crashing. Maybe some nullpointer / null reference issue ¯\_(ツ)_/¯

So for me the issue is resolved.
