Basically when I highlight an ability, either in my hotbar or directly in the abilities list itself, when I highlight it, it won't show the box to display what the damage is, what it does or anything, absolutely nothing happens. I am able to use the abilities, I just don't know what they do. This also applies to things such as mounts, teleport spells and so on. As far as I'm aware, items show descriptions, such as potions and food, just not abilities.

I have two characters, this bug is only happening on one of them, the other is fine. Any help would be greatly appreciated!
