Hello,
I'm running last version 18.7.5 and need switch firewall NAT Outbound to hybrid mode. After select Hybrod mode (or another different from default) and click save, I receive this message:

Fatal error: Uncaught OPNsense\Core\ConfigException: no valid config loaded in /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php:240 Stack trace: #0 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(182): OPNsense\Core\Config->checkvalid() #1 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(221): OPNsense\Core\Config->fromArray(Array, Object(SimpleXMLElement), 'rule') #2 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(221): OPNsense\Core\Config->fromArray(Array, Object(SimpleXMLElement), 'outbound') #3 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(221): OPNsense\Core\Config->fromArray(Array, Object(SimpleXMLElement), 'nat') #4 /usr/local/etc/inc/config.inc(156): OPNsense\Core\Config->fromArray(Array) #5 /usr/local/www/firewall_nat_out.php(56): write_config() #6 {main} thrown in
