Fancy Product Designer Multistep Product Configurator Another
When a customer saves a design, he/she can access that design from a different product page.
It loads the saved FPD product and design, but does not load the WooCommerce-product.
They can design expensive products, and lot it on a cheap one, to cheat the price and pay less.
Yes, the name would be different, but it would create a lot of confusion when we handle order and produce the item.
I think you have this problem when you store the users designs in the account of the user by enabling "Account Product Storage"?!
Do you have this option enabled? See screenshot.
