Loot and Crafting
It happens rather often since the new patch but every time after I finish a game, sometimes even before, when I click the button to go to the loot the game will crash, but the client stays open. So everytime the game crashes you have to reopen it and terminate the previous cleint (the usual message box that appears when you open 2 league clients). It's just really annoying it doesn't effect my gameplay though i.e. lag.
