I dont know why, but when I refresh my completion rate on random community decks or textbooks (I’m not studying them, just like to see how my progress compares), particularly grammar ones, even though the number of items in the deck hasnt changed (and I doubt the decks have significantly changed for things like Shinkanzen Master), I’ve been going down from, say, 21/200 to 19/200 or something. It is happening across almost all grammar decks. I doubt EVERYONE is modifying their decks, so I’m not sure what the cause is. Is this normal?
ETA: I observed this both today and yesterday, on the same decks even
