I am working on a big Drupal 7 commerce site and I have some issues with the commerce discount module on order discount. Both Drupal 7, commerce, commerce discount and rules is on newest stable releases.
When going through the checkout and a order discount is attached to the order (either with a discount code or direct) it's visible in the commerce_order_total_data field in the field_data_commerce_order_total table.
When going from checkout_review -> payment the discount is suddenly removed from this order and not getting back.
Cannot figure out what caused this neighter where it happens.
And a sitecomment here is that it works on dev and stage server, but not production (same code and every thing).
