[2021] Game constantly crashing

Hey @azure223! Apologies for any frustration caused by the issues you've experienced in game and with contacting support.

As a first step, please go ahead and give our basic PC troubleshooting a try.

If the issue persists after those steps, could you provide some more information on at what point in gameplay your game is crashing and when this first started happening?

The most common cause of saves not writing out is an antivirus app getting in the way. Which one do you use? Does that affect both local and cloud saves?

Add ck3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.  

TheMadJoker said: As for the saves, the ones that have disappear are the 3 autosave files. They've vanished from the "save games" folder

They were there but then disappeared? Or they never got there?

You are checking this by looking at the folder in File Explorer? Or just within the game?

Cloud saves you can see here:

store.steampowered.com Do they show there?  

So they were there once but disappeared? If so that is very hard to explain, as neither the game nor Steam deliberately deletes save files under any circumstances.

I can understand them appearing to be written out but not actually appearing at all (often an AV app getting in the way), but not being there but then disappearing!

They are not in the Windows recycle bin I assume?  

Autosaves only happen with non-Ironman games of course.

If it was a non-Ironman game, could it have been saving and autosaving to the cloud?

I am very sorry, then, I have no explanation for what has happened to you - whether they were there but somehow got deleted, or never wrote out at all.

All I can suggest at this point is you make a manual copy of your save just before or after every play session, so you don't lose too much progress were this to happen again.

My apologies for this problem, regardless of the cause!
