[2021] "This mod is not present on disk" subscription problem

Please try the following:

- unsubscribe from all mods
- delete the folder Documents/paradox/Stellaris/mod/
- delete the file Documents/paradox/Stellaris/mods_registry.json
- delete the file Documents/paradox/Stellaris/launcher-v2.sqlite

Add Stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list. You should add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.1/paradox launcher.exe to that list.

- subscribe to a few mods
- run the game up and see if those mods are now available to you.

I hope that does it for you!  

Eogen said: A less draconian approach can be to "verify integrity of game files" through steam. This will check for any missing files.

Only files that Steam put there. Files that the game created under the Documents folder will NOT be fixed by this, you need to do the full clean reinstall as I described.
