Sometimes creators would like to remove / re-upload assets, which is completely understandable.
In this situation, the asset in question would still be downloadable by people who have purchased the product, even if the product listing has become unavailable.
However, in collections this seems to work differently? I have purchased a few collections *and* assets from a specific creator. The assets are still available for download, but the collections all contain empty lists with a download size of 0 bytes.
This means that hypothetically you could buy an asset, not download it directly for whatever reason, and then come back only to see '0 bytes' when attempting to download it.
I would recommend CGTrader implement a system that allows collections to retain links to the files that were added to them, so that they function identically to assets that are removed (ie.: they are still downloadable with their proper contents)
Apologies if this is how it already functions, but this was my first experience with an existing product purchase outright 'breaking'.
