Ajeh's advice:
You would need to browse the table:
orders_status_history

and do a search for the:
orders_id...
In that table will be a field named something like orders_status_id. You should be able to change all instances of an id that you want to eliminate to an id that you still want to exist (and is not misleading in its meaning).

Do a database backup before you try anything like this, so you can restore it if you make a mistake.
