I hadn't noticed he switched the patch from newmems -> effective_mems. This needs to be changed back to newmems, otherwise we're depending on a derivative value set somewhere else in the code being correct instead of using what we *know* is correct *at the moment we need to use it*. So yes, go back to using newmems. ~Gregory
