I guess that the internal overwrite setting was missing, please try my
attempt [1] to fix that (fetch the r.basins with the extension manager
to get it, but since you are on Windows you may need to way till
tomorrow or simply modify the Python script at your end with a text
editor - just add one line).

Please let us know how it goes,
