I’m trying to earn the Legend achievement and after I beat multiple missions, solo, on Legendary, it’s telling me that I haven’t beat them on Legendary and that I’ve only beaten them on Normal (which is something I had done previously). What gives, though? It took me so long, and these were the last missions I needed, and for absolutely no reason, I’m not getting credit for them. How can I beat an entire mission on Legendary (four mission actually) and have it just not record that? This is very frustrating, to say the least.
