Playing as a Crusader (sword & shield)
So I just finished killing a Nurgle Dreadnaught, and I was exploring the UI. I clicked and switched from sword & shield to a two handed hammer, and realized I didn't want that, so I clicked again to switch back. Game froze, but music was still playing. I tried to alt- tab, would not bring up windows or any other windows. Ctrl-alt-del would bring up task manager, but not show it. Black screen with music playing and the in game pointer was all that would show. I could not do anything except hard reboot.
