script fail to move results from grass' temporary work are (Appdata).

I expect this is associated with the message: 'r was unexpected at this time'.

C:\OSGeo4W64\bin>g.gisenv.exe set="GISDBASE=C:\Users\user\AppData\Local\Temp\processing0fe29e2ca2af4404b4455312c20274a5\grassdata"

C:\OSGeo4W64\bin>g.gisenv.exe set="GRASS_GUI=text"
r was unexpected at this time.

C:\OSGeo4W64\bin>for r in $(g.list type=rast pattern='tmp15433306485454*'); do

Yes, it is different. It mostly works, but fails trying to copy the results from the temporary Grass working directory to user specified output directory. I had the same problem with r.texture, so I assume it is a generic problem with the grass toolbox functionality.

I can still view the results if I use Grass and point it to the temporary dataset.

Note this was observed in 2.18.26, which cannot be selected from the drop-down when submitting an issue.

GRASS plugin or Processing/GRASS?
