I don't know if this is normal but I am currently battling Blood Bat and I am able to attack twice and everything works fine. I try and click a weapon, a potion, or a spell on my third turn and the only thing I can click is the "Make Your Turn" button. When I try to click the other buttons A Red circle with a diagonal line through it. I haven't battled in quite a while so I am wondering if this is a bug or not.

That was it. It's the first time that has happened too. Is it an update?
