Didn't answer a question, but there's no red in the mastery levels in the answer panel to reflect a decrease in level (it was a definition to kana question):
All of the above should be fixed except: 1. @htatsuha - if you are seeing thinner radicals, is it perhaps due to a font change? Could you try a comparison between font settings? 2. The no drop does not appear to be an issue with beta, just an issue in general. Next time it happens, please send an in-quiz report. Thanks!
@leetmotif - those are surprisingly frustrating, but I think I've got em down. @mysticfive - let me notice if you see a pattern there, as I cannot figure it out. Additionally, sending a quiz report might alert me to something in the next question that is preventing it from appearing. If you know how to get into the web inspector, I'd love to know if anything is popping up in the console.
