There’s a bug on platinum difficulty where my fireball doesn’t work. I click it to cast, the cursor turns into a book, and when I aim, the creatures aren’t even highlighted in blue. I cast it, it explodes, and it’s like nothing happened, but the mana is still spent. And it doesn’t even deal damage.

P.S. No, maybe I’m just used to Heroes of Might and Magic V, where the fireball hits an area, and that’s why I’m hitting between two soldiers. But then it wouldn’t work at all, right? And the “target” still isn’t highlighted, even if I aim at just one.
