By the client do you mean the app? Do you know if you're trying to download it directly from the Fortune-499 page or from the bundle page? I know that itch doesn't actually add the games from the bundle to your library until you tell it to (to avoid flooding your library with stuff), so it won't give you a download link on the game's page and you need to find the game in a separate bundle page to get the download link (it seems to work this way both on the itch site and on the app, from what I can tell).
Well, it seems to have fixed itself overnight and I was now able to download it, so I'm not sure what caused it. Maybe itch was just overloaded.
But I'm adding a screenshot of the page I was on, basically when I was trying to download it yesterday the dropdown was just blank, I didn't have that issue for any of the other couple dozen in the bundle that I downloaded. Thanks for getting back with me though!
Right now the dropdown is only showing the music file but I think that might be because I already downloaded the exe itself
Note: Projects in this bundle are hidden in your library by default until you first access them in order to avoid flooding your library. You can return to this page at any time to access any projects you wish to show in your library.
