Lesson shows 0% new words and 0 LingQs

I don’t know what happened, but last night I was reviewing the vocab in a lesson with which I must have had around 100 LingQs. After exiting the lesson, LingQ now shows I have 0 new words in the lesson and also 0 LingQs. When I open the lesson though, I am greeted with a bunch of blue words even though I know these are words I have LingQ’d before. Please help!

That sounds very strange. Sorry about that. Can you email the lesson url and details to support at lingq dot com? Also, if you could send a screenshot that would be great.
