I managed to turn off the computer before 3am!
This miracle brought to you by me installing a bad combination of C:S mods, causing the game to crash on start up, so instead of fixing that, I loaded up Rocksmith for the first time in almost five years, plugged in my bass, and tore my poor little fingers to shreds*
*or, you know, made them a little sore because it's almost five years since I played my bass...
