It was checked. For some reason swapping the default music for my own resolved the issue. As for saving, I spam ctrl+s after every action and got the same results for the walls.
Also tried making new objects and atatching sprite "renerer"s to them. At first I didn't attach a sprite and the object returned a null reference error. I tried using a platform texture as a place holder yielded this:
This image doesn't exist anywhere in the texture files. Once again the issue resolved itself from using my own assets. Partially. It seems the y and x values for images get swapped in the editor.
It's problably related to why the walls keep shifting.
