Words learned was 1220 en is now 0.
Don't worry: no words are lost. We're dealing with a traffic spike and turned that feature temporarily off to keep the site up and running. We'll bring it back soon. Sorry for the inconvenience!
I hope the traffic spike is not the result of to many visits on the site, because with new languages it will only increase.
I'm going to post here as well since I don't want to start a new thread, but mine also went from 765 words to 0.
