Fixed, thanks for reporting.
From 30 seconds before a stable entry times out, a unicast requests are sent (only if the entry is still used for TX).
From 15 seconds before timeout, broadcasts are sent.
Not a real sophisticated algorithm, but it should do the trick, given that this is only a network bandwidth optimization.
