Client Bug

Every time I open the LoL client and I fill in my username etc the client acts really weirdly. I log in, and get the home screen (with the patch notes, friend list etc etc) then it crashes. Then it starts again, and it does this a couple of times. Also when you try to click a role while the client is spacing out, the icon of the role pick thingy will appear outside of the client on your actual background. Not that big of a deal, but it is kinda weird. Thought I was banned at first lul
