Yep, now it's working again.
Maybe keeping the nr of relays I'm connecting to down to maybe 5 (or something like that) would make Damus less capricious because there is less to handle (less memory usage).
Discussion
Disconnecting from relays in Damus deletes them from the list? Why, oh why?
Connecting to fewer relays maybe feels a but snappier, but maybe that's just my imagination.
No issues solved though. My "profile page feed" as displayed by damus is still very much just a fraction of what exists on the relays. 🤷🏻
