Thank you Geoff,
we’re taking a look to the plugin you suggest us,
but unfortunately is not something that can help us for the moment.
I’ve also tried different “paths” in creating the order (reduce the line item stock before/after saving the order; mark the order as completed without go through “attending payment” and other statuses), but the result is always a discrepancy between the two stock variables.
Looking forward to hear from you when a fix is available ASAP.
Regards.
