[Qgis-user] Bug or Feature - QGIS 3.2 raster styling

[Shawn Carter]

Sure.  https://1drv.ms/f/s!AhIPPYddAyx1gdsPGUUrwQMwtCGqOA

In that web share folder you'll find a GeoTiff with values ranging from -1
to 1.  The second file is a style file with three classes.  If you remove
the middle class, my QGIS will quit displaying any values...add a third
class it works.
