I have my own vocabulary list that I regularly update. It is the following:
Since recently I have the problem that I cannot learn any new vocabulary! It seems there is a “phantom word” in Level 41 (the one called Lesson 31), since if I look at the details of the level then I already learned all the words in there, but the green progress bar still claims that one of the words was not learned yet. When I try to learn the claimed remaining vocabulary of this level then I get an error message stating:
Whoops. Could not load the session. Sorry.
Where did the phantom word come from, and how do I get rid of it?
I had a similar problem with one of my courses. It actually helped me to delete a (random?) word, save and later put the word back in. I have no explanation for that but it helped me. (Causing this in the first place seemed my ignoring and later “unignoring” some words in a given level).
I had a similar issue with another course, with the same message, and I tried ignoring the words that make that issue. Maybe you could do that, or even ignore that entire level.
well I cannot really ignore the word that’s causing the trouble, since it’s a phantom word, which does not appear in the list of words at all. It just claims that there is another word to be learned in that level, but it does not actually exist. Ignoring the level is also not really an option since I need to learn these words for my language course
Yes indeed! That worked! I copied all the words and deleted the old level. Quite a hack, but it works. And you might think that memrise would like to repair such a bug. But no reaction from sending in bug reports whatsoever.
