The Group I moderate uses members' Display Names (and other things) to enable members to download technical documents from an Archive hosted completely separately from Groups.io. Members are required to submit a request form which includes their Display Name (and other things!) with these being checked against a list that is downloaded from time to time. If the details don't match then they don't get the documents.
Earlier this week we received a request from someone whose D/N did not match the records, so he didn't get the documents. However, when I delved further I found that (a) his registered D/N indeed did not match that he had given on the request form, but (b) the Activity Log showed that he had edited his D/N earlier in the year to that he had recorded on the request. In other words his registered D/N did not match what the Activity Log had recorded.
After some head scratching I asked him to edit his D/N again and this time everything worked as it should. I am unable to work out what might have happened; I wondered if he had "edited" his D/N but omitted to save the change, with a sort of halfway stage resulting. However, I have not been able to replicate this anomalous behaviour using a second membership that I have on the same Group.
Has anyone here got any idea what might have happened to cause the Activity Log to show an action that hadn't actually taken place?
