Missing Processing Tools in Vector Menu - #QGIS 2.16
According to ▻https://hub.qgis.org/issues/15265, the GDAL tools might get lost if you have the processing tools installed as an external plugin.
Since some time, it has become a core plugin, so no need to be in the users .qgis2/python/plugins/processing folder. You can remove that savely.
