For some reason after doing a review session on Flaming Durtles in which I reviewed the Hills radical, it kept showing up as unreviewed. I decided to check Wanikani itself and Wanikani says I have no reviews. The Hills radical shows up as greyed out (as if it is still locked on the Level page), and when I hover over the radical in the Dashboard Apprentice userscript display, it says it is available now. When I try and Browse level 8 radicals in Flaming Durtles, it no longer lists the Hills radical.
I had no prior issues with the Hills radical that I knew of (I got it to Apprentice 3 without issue). Is this some kind of bug that can be caused by the Flaming Durtles app?
