I don’t know if this is the correct place to report a system error.
The work for https://bookbrainz.org/work/2a05086b-15cd-42bc-9158-833a95b85922 lists the Edition To-morrow. When you click on the Edition it returns a 404 ‘Edition not Found’: https://bookbrainz.org/edition/b56e35b7-7fce-4e27-8f7c-a3c56bba358f
I see what the problem is!
It is listed as an Edition entity, but instead that BBID is for an Edition Group: https://bookbrainz.org/edition-group/b56e35b7-7fce-4e27-8f7c-a3c56bba358f
Most likely, this is left over from an old version of the relationship editor that somehow must have allowed user to enter that invalid relationship: https://bookbrainz.org/revision/2544
I’ll correct the relationships as needed, thanks for reporting!
