Wallpaper Glitch

[BlueSpark]

Right after accidentally activating the puzzle that changes your desktop wallpaper, I moved the game window and it closed on me. When it reopened, it apparently hadn't saved anything since arriving at the Glen, but my wallpaper was still that purple box combination. The game was still apparently in "puzzle mode" and closed again later when I moved the window, but returned to normal after freeing Alula. Unfortunately, my background didn't fix itself. I tried manually resetting my background, but the black bars that were where the image ends are still the dark purple from the puzzle picture.

Here's a poorly edited screenshot: http://imgur.com/a/pzd1U

Anyone know how to fix this? I'm running Windows 10.

When you moved the game window it looks like the game crashed, for some reason. Anyways, here's how you can change your background color, which is a little trickier on windows 10 than older versions of windows, for some reason:

-In the search bar in the bottom left type in "Run", then select Run (desktop app).
-This will popup a Run dialogue with a little textfield that you can type into. Copy and paste this in:
control /name Microsoft.Personalization /page pageWallpaper
Then hit "OK" in the window.
-This will open up the Desktop Background dialogue in control panel. Hit the blue text in the bottom left of this window that says "Change background color" and use this to change the color from purple back to black.
