Words I haven't learned

[ashuri]

Hello,

Don't know if this has happened to anyone else (though I suppose it would have by now), but lately while I've been practicing I'll get problems with words I never came across before. Normally this wouldn't be a problem except 1) They're verbs, 2) It's multiple choice, and so 3)I can't check the meaning. It's frustrating because, for example, "I talk while I eat" yields 2 correct answers - one I know and one I don't, which knocks me down a heart. I haven't seen these problems before today - is there a glitch in the system?

This was a bug that has now been fixed. Sorry about that!

This problem seems to have resurfaced for me.
