My subbed addons are broken

When I launch Gmod, and go into the addons, all of then are there but show no thumbnails or author names. They also have -218,810,000 rating. When I click on the header of the addon, steam says there was an error processing the request and that the addon was removed by the author. Please help.

Answered yourself right there. It could also be that the addon creator hasn’t accepted the new workshop Terms & Conditions.
