We study a non-semi-stable locus in a Hecke stack, which appears in Fargues' conjecture on a geometrization of the local Langlands correspondence. We find that a generalization of a diamond of a non-basic Rapoport-Zink space at infinite level covers the non-semi-stable locus, and show a twisted version of the Harris-Viehmann conjecture for this generalized space under some HN-reducibility condition. We show also that the cohomology of the non-semi-stable locus with coefficient coming from a cuspidal Langlands parameter vanishes. As an application, we show the Hecke eigensheaf property in Fargues' conjecture for cuspidal Langlands parameters in the GL(2)-case.
