A client's site has been running for three years with order IDs being consistent with sales_order
table's entity_id
. A month ago, three order IDs were skipped all on the same day but hasn't happened again since.
I've read that missing/skipped order IDs is no cause for alarm though as I understand it, they should still appear in the quote tables. They were not there.
There weren't any changes to the step value, unless Magento can change them on its own and then revert back.
Is there any other reason for order IDs to get skipped?
