ARGH! I had wondered why I had a review for 首位, which I was sure I had never seen before but was almost all the way to guru. Had me questioning whether there was a bug that affected other items as well, or whether I had been doing lessons/reviews in my sleep. The label/tag thing also kinda gaslighted me.
When changes like this occur, it would be nice if they put a notice right up front our dashboards, rather than expecting everybody to constantly check the forums or the blog. And maybe put a notice on the item’s page explaining that it recently changed?
