Fix Crusader Kings 3 Out of Sync Error

If you have got the Crusader Kings game no longer in sync error message, there are certain things you can do. The error mostly arises after a recent update or during the initial days of the game launch. One of the probable cause of the error could be an issue with the server being overburdened with the large number of players. As such the Crusader Kings 3 Out of Sync Error may resolve on its own.

However, some players have reported that running the game in Singleplayer and saving it before loading up the multiplayer seems to bypass the out of sync error. Hence, launch the game in Singleplayer mode and save the game. From the save game, load the multiplayer.

Another fix that’s revolving around is to save the game after the game no longer in sync error message and then you start a new MP game from the save. This works when the error occurs as soon as you launch the game.

On the Steam Community, some users have suggested to delete the game files and it seems to work to resolve the error. Go to Documents > Paradox Interactive > Crusader Kings III > Map. Once you are at this location, delete the navaldist_cache and navaldist_cache_chksum files. When you start the game, these files will automatically download again. Sometimes if the error message appears again, you need to repeat the process of deleting the navaldist files.

When the internet connection is weak or you are running the game on a PC that does not meet the minimum specification for running the game, the error can occur. Therefore, when you get the Crusader Kings 3 Out of Sync Error, verify that your internet connection is active and persistent.
