Upgrade to RC1 successful

[OPNenthu]

Maybe "Allow manual adjustment of DHCPv6 and Router Advertisements" was used on those LANs (also a bit earlier in time) which has led to several code problems over the years.

Indeed, it was used in the past.  I maybe even had it checked with Dnsmasq acting as the RA daemon, but the radvd service on all the interfaces was disabled.  I wasn't aware that after migration from ISC->Dnsmasq that I needed to also uncheck this option.

Still unclear why only those two interfaces in the screenshot showed up in the radvd service and were enabled, when I had several other interfaces configured identically.

I took a snapshot prior to the upgrades so I can roll back and try to reproduce... if that's helpful?  I could also save a copy of my config from that version.

Did you remove it from the GUI or via command line?

I uninstalled it from the GUI.

If you have the time in the middle of a major release progressing, could you elaborate on that? This is my default setup literally everywhere.
