I'm wondering why we should panic here.
https://github.com/ethereum/go-ethereum/blob/master/p2p/discover/table_reval.go#L173~L175

if !source.remove(n) {
	panic(fmt.Errorf("moveToList(%q -> %q): node %v not in source list", source.name, dest.name, n.ID()))
}

If the source list doesn't contain the node, just leave a warning log will that be ok?

}

If the source list doesn't contain the node, just leave an unexpected warning log will that be ok?

so i need change the source code and rebuild again?

@NathanHo1024 Please wait a bit, we will investigate the panic.

As now, you could downgrade your node to latest release https://github.com/ethereum/go-ethereum/releases/tag/v1.14.3
It should work without issue.
