You can't click on spots on the portrait that have numbers on them, so +stats blocks casting. Quickcasting is especially bad because you can only click on the leftmost 1/4th of the portrait and the rest doesn't register at all. I like casting a few things with quickast onto the portrait in certain situations, particularly Eul's Scepter and salves so I hope it gets fixed. Thanks!
