<ul><li><strong>Status</strong> changed from <i>Feedback</i> to <i>Closed</i></li></ul><p>Source of problem: my meddling with the shapefile had caused a ".qix" file to be created. Overwriting the spoiled files with clean ones from CDROM did nothing as they don't have the qix file. More in-depth info below from Giovanni; this posted here for searchability in case some other unlucky sucker runs into the same problem!</p>
<p>"the qix file is the spatila index. It safe to remove it (and eventually create a new one) and in fact it is the source of the issue. Once removed your edited shape is ok.<br />Apparently the index was corrupted or maybe it is qgis that corrupts it."</p> QGIS Application - Bug report #9408: Layer disappears when zoomed in past 'layer extent'https://issues.qgis.org/issues/9408?journal_id=475842014-01-22T11:45:44ZGiovanni Manghigiovanni.manghi@gmail.com
<ul><li><strong>Resolution</strong> set to <i>invalid</i></li></ul><p>If you have evidence that qgis creates bad indexes or that corrupts them, then please file a new ticket.</p>
