I was really confused since I didn’t remember that kanji and thought maybe I’d somehow forgotten it. Sure enough when I went to the page I actually didn’t. I’m not sure what’s going on since I’ve never experienced this before but I figured I’d report it.
I just got this as well. The kanji for 会 and 答 even though I’ve only cleared the 会 radical twice. The vocab that’s activated includes kanji that haven’t had a lesson for either.
