[2021] Mods not updating

I don't know why you have this problem, I see mods update in the launcher for various games all the time.

Are you on launcher 2021.1 or some earlier version?  

When that happens do you find the first two steps you mentioned above rectify the situation, even for a while?  

Frankly, me too! While we've had various issues with mods and the launcher, not this particular one so far as I know.

When did this last work?

Does this only affect this game? Or also say CK2 and EU4?

In the Steam settings-cloud , is Enable Steam Cloud Sync ticked?

As you are now on launcher 2021.1 you'll need to add that new exception to AVG.  

Well no, the 2020.16 file path does not contain the 2021.1 launcher .exe ! Each new version makes its own appropriately-named new folder. Do you not see a folder with 2021.1 in the name just there?

That's the wrong path, you are missing the /programs/ part. You found the 2020.16 sub folder here, as 2021.1 runs there must be a similar 2021.1 folder too, with the .exe in it!  

zulu9812 said: I found it and added it to AVG exceptions, but it's made no difference. Still having to manually re-subscribe to mods to get them to update.

I don't know then, I can't think of anything else that would cause this. Did you also add steam.exe and stellaris.exe to its exceptions?  

Then we seem to have run out of possible candidates for what is causing this problem on your machine.

Do you have access to any other machine to test this one? Or can you make a new Windows user on this machine and test under that?
