Vocabulary seems stuck
I have done a lot of vocabulary practices the last days (over 100).
Now it seems that the vocabulary is stuck. The last 15 practices or so, I got the same words over and over again.
Before, I would get the same words for 1, 2 or 3 practices, and then I got new ones. Now it has been stuck on the same words over and over again, and it doesn't seem to load new words even though I answer them correctly all the time!
What's happening? My account is 'fbaa' and I am learning spanish.
