Resetting the sim made no change, and neither did resetting the lot, for they're all spawning outside of it (although i did try). I've actually dropped a meteor on them, but it fell on the furthermost edge of the lot, or, more precisely, it's radius ended just a step away from the butlers.
Did you specifically try "ResetSim *"? I'm not suggesting resetting the affected Sim, but all Sims in the hood, which would hopefully include all those butlers. If that is what you did, then I'm stumped.
