We study geometrical destabilization of inflation with the aim of determining
the fate of excited unstable modes. We use numerical lattice simulations to
track the dynamics of both the inflaton and the spectator field. We find that
geometrical destabilization is a short-lived phenomenon and that a negative
feedback loop prevents field fluctuations from growing indefinitely. As a
result, fields undergoing geometrical destabilization are merely shifted to a
new classical configuration corresponding to a uniform value of the spectator
field within a Hubble patch.
