Game-breaking (Computer-breaking?) Nexus siege bug
Hello, i was playing a casual game of Nexus siege when, at the attack/defense swapping stage the game crashed. Bugsplat. I thought oookay and reconnected. The screen turned black and staid there. I shut down the league of legends process using process manager, and thus the game promptly started loading. (?) When it entered the game, i couldnt set the window to focus, but i also couldnt minimize, shut down or log off. the game forced my computer into a perpetual dead end between focus and lack of focus - not allowed to actually manipulate the game, but also forced to watch the screen without being granted access to ANY commands whatsoever. I had to force a shutdown by holding down the power button for 30 seconds upon which my computer emitted a horribly loud beeping noise before actually shutting down.
Video proof provided, sorry for the utterly cancerous quality but it had to be taken with my phone, as my computer was left completely unresponsive because of the League client.
How can i upload the error documentation files so that this problem might be fixed? I wouldnt want this to happen again in the future, not to me or to anyone else. I lost a good two days (approx. 30 hours) worth of work because of this.
