We recently did an update to 0.19.5

Along with this came a bug that makes hidden communities not function properly so that they will still appear in the all feed

I have reported this on the lemmy repo and once the devs fix that bug our all feeds should go back to normal (but for now content such as politics and bot communities may appear for a bit)

Heres the bug report if anyones interested in that https://github.com/LemmyNet/lemmy/issues/5074
