  We find that in 6d maximal supergravity there are 3-loop order amplitudes
with non-vanishing soft-scalar limits and anomalous $E_{5(5)}$ duality, induced
by a 3-loop UV divergence. If the relevant non-vanishing soft-scalar limits
would be detected in 1-loop amplitudes, it would be a 1-loop precursor of a
3-loop UV divergence in 6d.
