and now it looks like the patcher's borked because it'll get stuck on a percentage (83.2% for me) and no matter how much more data is downloaded it doesn't move.
Same problem but at 86.1 %. task manager shows it is still downloading data but the progress bar is stuck at 86.1 %. I did notice if I canceled the patch and restarted it without exiting the client it does update the download progress a little, think I was at 83% before canceling and restarting.
EDIT: Dont try above. Just did it again and dropped me back to 85%
