In the course http://www.memrise.com/course/85985/step-by-step-welsh-for-beginners/, the very last item on the last level is “Ân nhw”. This shows up as a tapping test with the first word split in two, as “” “n” “nhw”, which is clearly incorrect. “Ân” as a single word does not show up in the options. Furthermore, if I tap “” “n” “nhw” in that order the answer is marked as wrong.
