I don't battle often, so I don't know if this a known problem, or if its just a problem with my computer, but I can't see the freezing icon. I don't know if I've successfully frozen an opponent until the next turn when they do 0 damage and 0 healing. I also can't tell when I'm frozen, except that I can't click an attack.

Sadly the icon has been broken for quite a while now actually.

thanks for the info. Annoying, but at least I don't have to check my computer to see if its acting up.
