[Bitch] Why have half of the addons not viewable?

I can’t find anyone else mentioning this anywhere.
A lot of the popular mods are not viewable right now. My friend recently got gmod 13 so I’ve linked him everything I have so we can play properly together but 8/10 of the addons are no longer available but are still listen for some reason.
What’s going on?

Etc. They don’t exist now?

Upon further inspection and trail I found out you can still subscribe on the homepage even though they ‘don’t exist’.

I’ve noticed this too.

I think it’s probably just because Steam Workshop is still pretty beta. Hopefully it’ll all be resolved before gmod gets updated to 13 officially.

Hopefully? I was so close to getting the mega-upload achievement then this shit happened. Now I can only get subscribers…

This should be prioritized?

This only happened to workshop addons uploaded before a certain date (over a month ago for sure). Hope that helps.
