Fantasy & Science in German

why is it that on four consecutive times the lesson stops complete progress at a given lesson starting with :the aliens cannot only travel...The result is I start the lesson again and depending where that sentence appears, DUOLINGO freezes.

Maybe you can try "to clear the private data in your browser", another browser or another device? I have just strengthened this skill (including "the aliens cannot only travel ... "), but there were no problems (Duolingo web version, Linux, Firefox browser).
