Older manifests give a 404 despite being listed and previously available

[djgaven588]

Hello! So I am having an issue with DepotDownloader. In the past we used an older version of DepotDownloader and were able to download files for Robocraft dating back to the beginning of the manifests available. After an update with something DepotDownloader was giving an error when attempting it.

I updated to the latest version, and I was still getting this error:
Encountered 404 for depot manifest 301521 5813209191973149983. Aborting

I believe someone else was able to download the files on that day using the latest version of DepotDownloader, but I have as of yet not been able to download it.

We use the following for the manifest:
App: 301520; Depot 301521; Manifest: 5813209191973149983

Newer versions seem to work up to a certain point, however this does not seem to correlate to the first version I downloaded on my account and simply a range from the latest.

Any idea what is going on here? Perhaps we are missing some sort of parameter that is needed when accessing these older archived versions, or they aren't available in the region the program is trying to use.

We use DepotDownloader to assist users in setting up an older version of Robocraft, and need this functionality to work in order to make the process as easy as possible. So any ideas would be of great help!

EDIT:
Any updates here? We are still having difficulties getting DepotDownloader to download older manifests. Newer ones work, but we need to be able to download something 6 years old.
