Duplicated Orders on Import

Similar to these three threads –
https://villatheme.com/supports/topic/order-import-issue/
https://villatheme.com/supports/topic/order-import-shows-error-and-duplicates-orders-2/

And almost exactly the same as this thread – I am also on wpengine – https://villatheme.com/supports/topic/order-import-shows-error-and-duplicates-orders/

Essentially the orders progress bar stops working and the orders constantly duplicate.

I have wpengine also looking into the issue and escalated my bug as well as the above authors bug.

I just took a backup of the website. Please purge the old order data when making the fix.
