SAME!! i don´t know what to do...

Its a steam Bug so far i read that

If you had a normal amount of mods you can use the Loadscreen mod to see what mods are missing, if you had a ton this will be ugly to do

Only good sollution is sadly to make your Subscribed items a collection BEFORE you have the bug. (thats literally one click)

Had not played for about 24 hours and I find today (9:00 AM Eastern Time 5/21/24) that all my workshop subscriptions are gone - as if I unsubscribed to everything - which I did not do. The workshop file on my PC seems to be intact, so I immediately copied it to another drive. Problem seems to be by steam account. Is there a way to restore the subscriptions from maybe 1 or 2 days ago?

If you use Skyve (which you should if you have any mods), you could create a text file with all the Steam IDs in the workshop folder you still have, and then feed that list to Skyve to resub to all of them at once.

If you had a lot of subscriptions, creating such a text file can be done in a command prompt, if you know your ways around a computer a bit.

And indeed make that collection when you have it fixed, as Priest suggested above!
