Small but annoying visual Kai'sa bug.
There's a visual Kai'sa bug that is very easily reproducable and quite annoying to say the least. You need to have for example 99% bonus attack speed ( so you need 1% more for the evolution on your E ). Then, as you level up you get that 1% attack speed ( or even more ) for your E evolve so you evolve it. After that, a strange yellow thing sticks above your abilities on the HUD and just sticks there. It's quite annoying. It's very easy to reproduce this bug as you can get 2 Curved Bows and 4 Daggers which results in 50% + 48% attack speed which is 98% ( of course you do while level 1 and without predicion anywhere in your runes ). You level up, get your evolution, evolve and you just reproduced that bug.
