This a relatively minor thing but now that I noticed it I need to ask for help.
About three days ago I did a chunk of lessons, mostly vocab, including two vocab using the freshly unlocked 島 kanji. Tashirojima stood out to me because 1) cats! 2) unusual reading. I braced myself for a leech with Tashirojima, and so it stuck in my brain that I had learned about it.
Fast forward to today, and more importantly to the point, I realized I haven’t reviewed Tashirojima once. I’ve reviewed Hiroshima three times already and still have yet to see my cat island. Here’s a screenshot of my Tashirojima item page:
It’s just one vocab and I’m not gonna die without it, but now it makes me paranoid that some other lessons may fall through the cracks.
