The general problem is that spell icons only appear as a blank (light grey) square.
I first noticed this in the spellbook. Each spell has three associated icons.
- The one on the right indicating base type (fire/magic/etc.) is fine: correct image and tooltip text.
- The one in the middle indicating target (caster/touch/etc.) is also fine: correct image and tooltip text.
- The one on the left, however, is just blank. The tooltip says "Select icon". Clicking on this brings up a panel with two sections: at the top it says "VMBlast Test Pack", followed by 69 blank squares; at the bottom it says "Classic", also followed by 69 blank squares.
When my character casts a spell with a duration, a blank square appears, flashes towards the end of the duration, then disappears.
Overall, the placement, number and behaviour of the spell icons seems to be correct; the only problem is that all of these icons are blank.
