Yes, I'd like to see that. I'd also particularly like to see the configuration history after it fails. The only thing I can imagine so far is that is fails to detect ena1 and somehow assigns all interfaces to the only remaining NIC.
But if that did happen it should drop to the interfaces assign prompt because the config contains interfaces no longer in the system.
In the config you uploaded though both WAN and LAN are assigned as ena0 and that shouldn't be possible.
