  Er et al. (2021) recently proposed a two-planet solution to account for
eclipse timing variations (ETVs) observed from the sdB binary NY Virginis. We
tested the proposed planetary system for orbit stability using both numerical
simulations and chaotic behavior analysis. The best-fit orbits, as well as
those with parameters varying by the published uncertainty range in each
parameter, were unstable on a timescale much less than the presumed lifetime of
the PCEB phase ($\sim$100 Myr). suggesting that the proposed circumbinary
companions fail to provide a complete explanation for the observed ETVs.
