Oculus mode shifts collision meshes?

I was able to package my game successfully into an .exe file (Windows 64-bit). However, when using the Oculus the collision meshes I had set up and auto-generated seem to shift. The character ends up walking midway through a wall until it hits the shifted collision mesh. This only happens when alt+enter is pressed for Oculus Rift mode. When using the same .exe for use on windows, the meshes are honored and are found in their correct location. Any idea why/help?
