Sorry if this has been brought up before, I couldn't find anything about it by searching.

I created a word list of 190 words, and studied something like 150 words to complete it, and suddenly now it states i only have done 2 words (1.1% complete). If i go into the list, the word progress is not lost (the green squares) but the list progress seems to be.

What happened? Is there a way to restore my progress?

Had you recently changed your study part settings to include tones, pinyin, and definition? I noticed the list had skipped over those parts for the first bunch of words, I've reset the list to start adding from the beginning with these parts-- the list indicator will say 0% since that's it's current position of where it's adding from. It will skip over any parts already added as you study through the list, and your progress percentage for the list should quickly catch up once all of the parts that had been originally skipped over are now added.

Oh, yes, I did!! Thanks a lot! :)
