Hub Mesh loses IP address of remote after full shut-down

I have a new issue, and a work-around.

I performed a controlled shutdown of my two hubs which are participating in hub mesh. I needed to shut off power at the breaker to install some new dimmers. When I turned the power back on, both hubs powered up at the same time, along with my router, network switch, etc... They both obtained an IP address, and initialized. However, I notice that one of the two hubs was missing the IP address of the remote node. Both hubs use DHCP reservations on the router. The fix was to reboot the node that was reported with a null IP address.

This is not urgent as I have a workaround. I do rely on the hub mesh to be working though, as the one called Home Integration handles all network integrations (life360, hue, bond, etc).

Is this a known issue?

Is there a solution?

Thanks!
