You can download them on the patreon page you're redirected to. On that page find the mod you want and there it should say "download here" when you press that it should download right away. It also took me some time to figure out haha
Hi. I'm not sure if you still need this but I had a similar problem with the link and what helped was searching for the mod. The second link [Health Related Mods | a.deep.indigo] that popped up was the one that had the download link. It had the "download here" thing - also I just tried doing it again and now it appears normally and lets me download lol, but didn't at first
