I found a bug using entity translation with Commerce.
With entity translation enabled the following happens, if I place an order the billing info (and shipping info when enabled) is deleted. see these screenshots:
The entered data:
The expected result (entity translation disabled)
The data also doesn't get linked with the order, which is kinda what you want when you have a webshop, so you can actually bill your customers and send them their orders.
I tried updating to the dev version but that didn't change anything, I also tried different settings, but even when I turn all the options off, it's still broken.
I also enabled all permissions but that didn't help either..
Any thoughts on this?
