The other aspect was that this worked OK with the Oersted release, but fails with the Gauss release.  Since there were no significant changes in Multipole or AEILocalInterp between those two releases, the cause probably lies elsewhere (e.g. Carpet).

Jim, could you try running without symmetries, to see if the problem is related to symmetries?  Also, you could try setting the parameter CarpetLib::interpolate_from_buffer_zones = yes in the Gauss version?  The default changed from "yes" to "no" between these two releases.
