N2 - There are many single field inflationary models that are consistent with the recent Planck 2018 measurements of the spectral index ns and tensor-to-scalar ratio r. Despite good agreement with observational data some of these models suffer from having unregularized potentials which would produce a collapsing universe shortly after the end of inflation.
