I also seem to be created new cards with wild abandon trying to return the permissions to how they should be. There are now *self+*read cards that didn't exist a second ago and don't seem to do anything, except I've ruined the search results query that used to be working. And I don't know what's safe to get rid of. :(

The idea was just to make the *listedin card Read for Administrator only. But that hid all the query results too. I've been trying to put it back, but it just keeps making more cards and showing the above error.
I don't know if anyone did anything, but this seems to have healed itself.
I didn't do anything, but the above looks like a cache error. Something probably cleared the cache.
