Impossible to assign/enable new LAN interface if previously doesn't exist
Prerequisite: a system with a single NIC, freshly installed with pfSense 2.3-Release.
Boot pfSense normally, assign the single available interface as DHCP WAN.
Access the web interface from another PC.
Go to Interfaces > Assign, add a new VLAN, assign a new interface to that VLAN. It's going to be named automatically "LAN".
Go to LAN interface, select "Enable interface", at IPv4 select "Static IPv4", at IPv6 select "None".
At IPv4 Address put something like 192.168.1.254 /24, press Save.
The following input errors were detected: The DHCP6 Server is active on this interface and it can be used only with a static IPv6 configuration. Please disable the DHCPv6 Server service on this interface first, then change the interface configuration.
Go to Services > DHCPv6 Server & RA, to chekc DHCPv6. Error displays:
The DHCPv6 Server can only be enabled on interfaces configured with a static IPv6 address. This system has none.
Go back to LAN interface - still not possible to enable it.

I pushed a change to unset dhcpdv6 on LAN when LAN's removed as I knew where that was offhand. I'm not sure if that's enough to completely resolve the issue, haven't had time to review in detail.
