Europa Universalis IV Dev Tracker

Best to lodge a support ticket at paradox.zendesk.com on that, as it will need to be dealt with by Paradox directly.  

Did you find what app or utility seemed to be causing this?  

Have all players check that all the Steam ports are open (NOT forwarded, open) in all their firewalls:

Steam Support :: Required Ports for Steam

As it happens with one Windows user and not another on the same machine, it must be that first user is running some app or utility getting in the way, has some Windows setting causing this (such as mouse trails), OR is corrupted.

In that user go into the Startup screen and disable everything in there and reboot, does it still happen?  

Are there any mods in use?

When you hit PLAY in the Steam Library, you get a mini-menu. In there choose Nakama instead of Steam MP - all players will need to do this.
Does that help matters?

I'm sorry that happened but I don't know why! It's a routine thing to do.

Did you try a new Windows user as I suggested?  

If you want the developers to look at this you'll need to post in Bug Reports forum - they do not read this forum.

And it will have to be a game with NO mods used in it ever.  

Anyone new posting here Please do a full clean re-install:

move any valued save games elsewhere
"uninstall" in Steam-EU4
manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders - In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.
re-install game in Steam, run a Steam Verify when done.
add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
run the game up to the main game menu then exit to the desktop again (to create the settings files)


THEN Right click on eu4.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.

THEN edit Documents/Paradox Interactive/EU4/settings.txt as follows:

Did you see this question?

grotaclas said: Is there maybe a war between two AIs which have colonial nations? That causes freezes in some cases since version 1.34.

Maybe attach a problem save file here to see if we get the same problem.  

This smells of a Windows or hardware problem to me, although why only this game I cannot say.

Make a new Windows user on this machine and log into it with that. Do you still get that same pattern?  

It's hard to understand why EU4 sees this and CK2 does not - they are very similar under the covers.

But if this has only just happened, Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders - In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.
- re-install game in Steam, run a Steam Verify when done.
- add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test with a new campaign, NOT any existing one.

Is that any better?  

Then they really shouldn't be showing as incompatible. Attach an affected one here please.

@grotaclas have you seen anything like this?  

If those are saves from 1.34.x you need to revert to that version in the Steam Betas tab. You don't need any code to do that.  

Please lodge a support ticket at Paradox.ZenDesk.com , and paste the key you got from Humble in there, along with a screenshot of the receipt from them showing you bought a pre-order key.  

I don't see any good reason for this in those files. You may as well update those nVidia and AMD video drivers though:

Download the latest official NVIDIA drivers

Was this in a campaign started under the new patches 1.35.x ? If under an older patch, you'll need to revert to that version in the Steam betas tab for the game, to continue it.  

Please attach here your Documents/Paradox Interactive/EU4/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/EU4/logs/ folder, attach here system.log , error.log .


Please report the temperatures of your CPU and video (GPU)
1/ before starting the game up and
2/ after say 10 minutes' play.
If your PC's vendor has given you no way of reading temperatures, install

Some stores sold keys for the the game before release day, but they were not actually pre-order keys.

Please check with Humble - do they believe they were supplied pre-order keys by Paradox? Or ordinary keys?  

Did you mean to post this in Bug Reports, perhaps?  

Right click on Documents in the left column of File Explorer, just under This PC there. Go to properties, location. What does it say in there?

If it says your Windows User Documents are held on OneDrive, that may be the issue - the game trying to write there while OD is syncing, something like that. Best to redo Windows settings so your User Documents folder is local, not on MS's cloud servers.
