Forward Shading stopped working

I have a plaid texture on a couch. When viewed in VR without Forward Shading on, I get some horrible artifacts when moving my head side to side. But with Forward Shading on, it looks fine. The issue is, it stopped working for some reason. But when I create a new level and drop that plaid couch in, I have no issues. Why would this only be an issue in one level and not another if its an overall project setting?
