Thank you for the fix!Anyone else experiencing this?
Also, I updated the download link with the russian fix, you can find it HERE or in the OP. Sorry for the inconvenience.
As for the mayor/baron/bishop uprisings - this bug has existed for a very long time. I remember it from, for example, version 1.4.2. Of course, the war ends with the death of the barony-level landlord.
