Hi,
All of my saved words and all of the statistics and user history have disappeared. Is this a bug or did something go wrong with my account ? Does anybody else have this problem ?

I had the same issue and then realised that Language Reactor now defaults to a language I’m not learning (Spanish). Switching back fixed the issue. Could this be the same issue you are having?
omg yesss, so easy 
didn’t think to check the language, it never switched before, thanks !!
