Error on credit memo saving

[Fel1xx]

Found weird issue happening while saving a creditmemo. It seems that method register() is called for creditmemo model, but there is NO such method in a class \Magento\Sales\Model\Order\Creditmemo

Stack trace:

Does anyone checking this?

[stevenvdp]

We also have this problem, seems like this is not a priority for Magento...
@Fel1xx I've found a PR where they simply remove the register() call, you could give it a try.
#2656

[NadiyaS]
