Ooh… I hope that’s not what I think it is.

Are these materials yours or default engine?

Can you open these materials in a completely new/fresh project?

I made the materials from scratch. Its frustrating because i cant seem to find exactly whats causing this, it seems to happen randomly when saving material changes.
