A contact on two servers at once was marked seen by each in turn: a sighting announced a contact change, every connection re-applied its contacts, and each re-application recorded the contact on its own server — another change, round and round, rewriting contacts.txt every time. Re-applying now only marks a contact that was never seen; the last sighting moves when the client appears. Sightings no longer write the file on their own either: they reach it in one save half a minute later, or with the next edit's save, and are flushed when the client closes.
