Sort Order and Shaders All Messed Up

I’m not sure if this is the right board, but today when I opened up my UE4 project, everything is rendering out of wack. The draw order of everything is reversed, shaders aren’t rendering correctly, and even editor sprites are drawn as a flat plane. I tried re-compiling all the shaders, but no change. This is even persistent on multiple computers. Has anyone else experienced this?
