[2023] Lions of the North DLC unable to be verified on steam

This is a cosmetic problem caused by a minor bug in the new launcher, the DLC is still available to you in the game.

It should be fixed in the next launcher update.  

If there are no mods involved, that sounds like a corrupted installation. Here's the complete clean reinstall process:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders
- 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

In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.  

Hmmm. Do you get this if you do a test install on any other computer you might have access to?  

I'm now told this will be fixed by an EU4 update at some point, I have no ETA as yet sorry.
