However the issue is *apparently* is being worked on by the developers of that website. This is an issue on steamworkshop.download's end. There are several games that are in the supported list but currently can not download the mods. Rise of Nations is a mod lovingly made by the Hoi4 Community, for the Hoi4 Community. We will no longer maintain a list of working games because ALL games are affected. Please only report issues that are from our script. All that we are doing is adding a button on steam workshop page that allows us to download mods that are on their servers, cached and all.

Secondly, most game mods are cashed which means while you may download mods from the website it will download an older version. I have reported that issue on their public forums, and the administrators are saying that they are working on it. editing anything you want without it being overwritten the next time you launch (since it will think it's outdated or something and 'fix' the files back). It's always better to have further control over the mods, ex. A tool to download addons on the steamworkshop by only giving their names. The error seems to appear when the mod file is larger than a few Kilobytes (not sure exsatally how many kilobytes) This is STILL an issue on steamworkshop.download's end, we cant do anything about it. I personally always prefer direct download & installation rather than Steam Workshop, only allowing some smaller mods through it. A small reddit bot that fetches steam workshop links for mods on RimWorld. Thanks to u/No_Climate7825 investigations it turns out the error 'Free Space Left' doesnt just affects all games but rather it depends on the size of the mod.
