Summary​

Multiplayer Crash and OOS problem.

Description​

We recently played a multiplayer game of Crusader Kings III with 10 players. Despite taking all known precautions, some players experienced crashes (without crash report) and out-of-sync (OOS) issues.

Here is a summary of our setup and troubleshooting steps:

All players used fresh, clean installations of the game via Steam.

No mods, third-party tools, or edited game files were used.

All OOS folders were cleared before each session.

Autosave and Steam Cloud were disabled.

Max FPS was capped at 60 for all players.

All GPU drivers were up to date.

Every player verified their game files via Steam.

Each setup was personally checked over Discord to confirm compliance.

Despite this, we started encountering crashes and OOS issues after approximately 30 in-game years. We've done everything suggested on forums and community threads, and for the first part of the game, everything ran smoothly.

We are confident that the issue is not on the user side but rather game-related. We understand developers often need to eliminate user-side issues first, but in this case, we have thoroughly validated all possible causes from our end.

We are providing the save file and all related logs for further investigation. We would appreciate it if your team could take a deeper look into this, as the problem seems to emerge after extended gameplay in large multiplayer sessions.

Thank you for your time and support.

Also there is this kind of court problem.

"Crusader Kings 3" is not a dynasty simulator — it’s a desync simulator.
Multiplayer collapses every hour. Paradox has had years to fix it. They didn’t.
Instead? They sell more $20 flavor packs while the core game rots.

Fix the damn game before selling new hats for Vikings.
