Bug - Deleting a network that is used in EAP ACLs results in broken EAP ACLs until rebuilt
Problem:
If you delete a network (on the LAN management screen) that is used in the Destination side of an EAP ACL - it does get removed from the ACL, but the ACL is left in a broken state resulting in configuration failures, and the inability to disable or delete the offending ACL (error banner at top of page when trying to do so)
To rectify this, you can edit the ACL, click select all networks, then click it again to de-select them, then select the networks required. This "repairs" the ACL and it can then be deleted or disabled successfully.
I dont know if the same happens on the software controllers.
