LAGG VLAN interfaces report parent interface no longer exists following the parent (LAGG0) being added under interfaces>assignments and later removed when clicking save. Adding LAGG as an interface on assignments page followed by modifying the MTU, MAC address or any other settings on the now present LAGG (opt) interface, enabled does not need to be set, nor does v4/v6 configuration type prior to save/apply. No error is presented but traffic ceases to flow on the children VLANs present originally when the unassigned LAGG interface was only shown under Interfaces>Assignments>LAGG. Deleting the OPT LAGG interface from the assignments page and then saving presents error regarding VLANs that previously existed as interfaces prior to any change to or the addition of LAGG0 in the assignments menu. Without making any modifications, saving and applying the VLAN's interface settings as well as the VLAN tag(s) seems to restore functionality.
