Alright, so last night I was able to sit with it in the corner of my eye landast night, and I saw it fail. So some more details, I was downloading New Super Mario U + Super Luigi U and it crashed on me four times. Three times it crashed while downloading. I wasn't touching the game pad or the pro controller, the screen was dim due to inactivity, and suddenly it would just pop to the "Goodbye!" screen and froze. I had to pull the power to turn it off and back on again. Then one time it oddly crashed when it was starting the download back up, moving threw the files it already downloaded. Every time it crashed I went into WiiUShell and deleted the previous file. I couldn't sit up with it to install the game, but when I got up the next morning, my Wii U was off, but when I turned it on the game was there and it ran great. So I think that's what happened to me. If there's anything else you might need to help you, just ask.
