This is gonna be a really quick update

This just fixed the export option in the walk animation.

For now, there's no loader when exporting, and it may take some time before the saving of the image dialog pops up.

But at least now, it will save the correct walking sprite sheet.

Note: 

The images may be off when rendering, and you may notice some artifacts and gaps. I'm working on laying all the image assets in one PSD file so I can polish them and to make sure they are seamless when assembled.
