  The ghost conjecture, formulated by this article's authors, predicts the list
of p-adic valuations of the non-zero p-th eigenvalues ("slopes") for
overconvergent p-adic modular eigenforms in terms of the Newton polygon of an
easy-to-describe power series (the "ghost series"). The prediction is
restricted to eigenforms whose Galois representation modulo p is reducible on a
decomposition group at p. It has been discovered, however, that the conjecture
is not formulated correctly. Here we explain the issue and propose a salvage.
