Steam Workshop refusing to download subscribed content

[Kalista]

Attempting to download a mod via steam workshop with it only giving me a 0 byte file. Followed the advice of the mod maker by subbing to the mod in question leaving the game launcher run for 15-30 minutes with it only downloading a dummy file with no mod attached to it. Posting this here since I was told that CK2 downloads steam workshop mods directly through the launcher.

It does, yes. I know that do sometimes take quite some time to appear, even days, for no known reason.

That aside, there is a limit of 50 or 60 mods at once - if you have more than that, you have to uninstall one to get a new one down.
