<p>When a refinement level is regridded, the outer region (ghost zones and boundaries) are invalidated, but PreSync validities are not properly updated to reflect this. A pull request has been <a data-is-external-link="true" href="https://bitbucket.org/eschnett/carpet/pull-requests/57/carpet-added-presync-support-in-regrid" rel="nofollow">created</a>. It still needs to also detect whether the grid functions are prolongated or not. If they aren’t, they should be set to `nowhere' instead of `interior'.</p>
