Missing textures on Oculus Go packaged game?

Hi All,

We are trying to ship our product and have hit a major snag. When I Launch to the Oculus Go all textures show as normal, but when I package THE EXACT SAME PROJECT WITH NO CHANGES WHATSOEVER, there are several textures that are missing in the level!

Any ideas as to why this weirdness is happening??

Also, the settings for packaging(ATSC) are to cook everything in the project.

Thanks,
