Hmmm... It's maybe the opposite, but here it is. I had this question
and I thought it's weird, because this reading is beyond highschool knowledge. But maybe it's JLPT? Or maybe there's a mistake in the JLPT list and JLPT students are only supposed to know 込む? When I type komu, 混む comes before 込む. Weird But anyway when I check,
I see 3 readings greyed-out that shouldn't be: mazaru, mazeru, komu
ok, 混む is elementary school level, I'm glad I brought it up, then. But the 3 readings that I mentioned are still greyed-out, although I've seen all 3 at least once. Or is there a minimum mastery level to reach before a reading stops being greyed-out?
Got another one, this time in 4196. Actually popped up last night, but didn't want to send a bug report until I was sure. Can do tomorrow. Here is an in quiz screenshot and one from the end of quiz last night. Even the sentences are gray.
