We’re switching to a hints system that allows answers that are grammatically/contextually incorrect to explicitly show as incorrect, but still have a hint/helper.
Previously, all hints were orange, regardless of if the answer was correct under other circumstances, or just completely incorrect in all circumstances.
So, to use your example, previously the “Let’s try a different particle” hint for 「なみえる」 would have been orange.
Now, 「なみえる 」 is explicitly marked as not correct.
Does that make sense?
Sorry I feel like I’ve done a horrible job at explaining
