Assets in Library but Listing Removed from Store

I noticed today that I have a ton of assets in my Library that have seemingly been removed from the store. The sellers still exist but the assets are inaccessible despite being in my library, and the asset links are dead. Example:

https://www.fab.com/listings/f4e16739-0906-4908-ae38-290025cc65e5

These assets all lead to dead links:

Meaning they cannot be downloaded, and no explanation given for their removal???

I’m not sure what’s going on here - maybe they were removed because of Content violations or otherwise, I really don’t know. But if there are paid assets being taken out of one’s library because they violated the store rules then (1) purchasers need to be notified so they don’t inadvertently include them in a shipped product and (2) Purchases that are not not-accessible need to be refunded to the extent possible (so you’ve paid for a product on FAB and they are now not letting you download that product…like, excuse me?).

Same for more assets in the Epic Launcher whose links lead nowhere:

What is going on here?
