Great course overall.
Though I have a problem with the last word in adjectives, “interesting”. It causes the android app to flag up with an error. So, I tried to use the web app instead but it only shows the word “interesting” for English but is blank for Elefen. When it comes to then displaying it as a question, both the question and the four choices are all blank.
As a workaround, I’ve I had to mark it with Ignore.
Edit: On level 7, the word “badly” is also blank for Elefen.
Edit 2: And again for the word “room” in level 8.
