Lost follows / follows not appearing in feed

[ovelny]

Before you start.

• I have checked the Common Problems page.
• I have searched the issue tracker for a bug that matches the one I want to file, without success.

Desktop (please complete the following information):

• OS: Debian 11 bullseye
• Browser: N/A (using fraidycat desktop app)
• Version: Fraidycat-1.1.7.AppImage
• URL you are attempting to follow: N/A

Describe the bug
Within the last few days, I've noticed that roughly half of my follows don't appear in my feed. They also don't appear when exporting JSON settings:

$ jq '.index[]' /tmp/fraidycat.json | wc -l
101

However, all of my follows still seem to be present in ~/.config/Fraidycat/File\ Storage/feeds:

$ ls -alh ~/.config/Fraidycat/File\ Storage/feeds | wc -l
224

I thought there was a pattern explaining the lost follows at first, as all the ones related to Reddit disappeared. But it turns out that many others are not showing up too, so I'm not sure what could be the cause.

Is there a way to restore them, or at least make an OPML export with what I have in ~/.config/fraidycat?
