Description of bug:
I have unit specific hotkeys enabled. I don't set any new keys for any hero, but if I go to a hero (in my case meepo) and enable quickcast, when I quit the game and restart it, quickcast is disabled for that hero.

There doesn't seem to be a workaround for this issue. I've tried toggling things unit specific keys to try and reset some internal state, but it's the first thing I need to do when restarting the game.
