I have observed three orders with the same `external_order_identifier`, but three different ShippingEasy ids. This becomes an issue when trying to track unique orders in ShippingEasy to tell whether I have already synced the order. This particular order does not appear to be split or combined.

Do order ids ever change?

For example, I have an order with a ShippingEasy ID `1195444993`. Later, an order with the same external_order_id has ShippingEasy ID `1199472183`. Finally, I see the same order with ShippingEasy ID `1201513973`. All three have the same `external_order_identifier`.

The strangest part is when I query the API later, I can't find the first two order ids. They appear to not exist; only the last id exists.
