I noticed (after a fresh nuke) that I stopped getting pinyin practice fairly quickly, despite being wrong pretty frequently. On the "vocab" tab, all P entries are marked to be 6 or 7 days out and ~75% learned, even ones I knew I got wrong.

I got to a point where I was just hitting "show" which turned the box red, and then clicking "next", but could there be some internal error going on that is marking them correct?

Hey, I see that mistake! It doesn't look like it's new, either (I could be wrong). If you just hit the show button, it looks like it's marking it wrong, but it forgets to mark it! Oops.

I'm out of time for tonight, but I'll try to have a fix early tomorrow. Thanks for the great debugging on this one.

Forgot to mention, but I did get this one yesterday.
