Interface gone missing from Rules menu of secondary

[whitwye]

With replication of rules working fine between primary and secondary, suddenly a minor rule change on the primary for the WAN interface has cause that interface to disappear entirely on the secondary from the Firewall > Rules menu of interfaces to view and edit.

Where would I go to recover from this?

Can't get their directly via the /firewall_rules.php?if=wan URL either.

Okay, after I re-enable the interface (I'd had it disabled on the secondary because of the way CARP keeps turning itself back on with rule changes – and there's other stuff to straighten out) it came back to that menu. Makes little sense to hide it though -- the rules should be available for viewing even if the interface is off.
