  The nucleon-like member $N(1685)$ of the speculative baryon antidecuplet
denotes one possible explanation for the narrow peak-structure around $W =
1.68$ GeV observed in the total cross section of $\eta$-photoproduction off the
neutron. If this baryon existed, it would likely to be seen in other reactions
as well. While the aforementioned peak, whatever its nature is, was confirmed
by several experiments, claims for signatures of the $N(1685)$ in other
reactions and observables are mainly made by V. Kuznetsov et al. using GRAAL
data. Their latest work suggests signals of both $N(1685)$ charge states in all
isospin channels of $\eta\pi$-photoproduction off the proton and neutron. This
contribution reports on challenging these claims with data from the A2 at MAMI
experiment employing photon beam energies from $E_{\gamma}$=1.43-1.58 GeV. The
$\eta\pi^0p$ and $\eta\pi^+n$ final states produced from a hydrogen target were
studied and new analysis cuts were tested in order to enhance a possible
signal.
