I have noticed a problem with retrofit on texts that have manual line breaks. When I try to accept the changes in Studio I get an error message (in German Fehler beim Einfügen der Marker für nachverfolgte Änderungen - presumably in English error on insertion of markers for tracked changes). I set up two identical files, one with and one without manual line breaks; only the one without manual line breaks cleaned properly, the other one generated the error message. I recently changed to Windows 10, which may or may not be part of the problem. Any suggestions?
