So I had Tsurukame open on my phone at the same time as the webpage, and I saw that there was one review in the queue in the app but not on the site. Weird, but maybe an updating issue. I opened the review, and it was 大いに which I then burned on the app. Because I didn’t feel comfortable with that, as I felt like I kinda guessed and then got lucky, I went back to the site to un-burn it.
And it doesn’t exist in the WK system. It’s not in the search or the vocab list for the kanji 大. A brief search of the forums yielded no answers.
I am so confused. Where did it go? Did I miss a notification of a content update? Did I fall into an alternate dimension? Did I burn it completely out of existence?
