Each save that records a batch also deletes, in the same transaction, the batches older than database.change_batch_retention (30 days by default; 0 or less keeps them for ever), with their records of opportunities. A client still holding a deleted batch gets 410 Gone from ?changed_after= and reloads the whole list, as for any unknown batch.
