GUA addresses have gone

[simpz]

I haven't changed my setup of interfaces or the ip6neigh config in a long time. But suddenly I see my GUA addresses have gone from "Predefined hosts", ULA ones are still present. I also no longer have any GUA addresses listed under the "Discovered hosts" now are all UNROUTED.lan.

The only options have different from the default example config file are:
option lan_wipe '1'
option router_name 'lanrouter'
option dad_snoop '1'
list fw_script '/root/ip6neigh_rules.sh'

I have OpenWrt 19.07.3 installed.

Found it. Even though I still had ip-full installed seemed to misbehave and use the busybox one.
Ran:
opkg --force-reinstall install ip-full

All is working now.
