Loss of PPP config after reboot

Our edge firewall had lost power today. When the router came back up, all of the PPP config was gone. Running 5.23 on an RB1100. The change log in 5.23 actually states this issue was resolved. I’m curious if anyone else has actually seen this issue in the wild (I’m sure someone has) and if it truly loses its config, ie needs to be complete rebuilt, or if the config comes back in an upgrade.
