FBX UV's messed up (From Blender)

So I had UV's working fine on this object, then I changed the UV's in Blender so I could to texture painting instead. Did the painting and generated the Texture map in Blender, but now when I export the new FBX (To update the UV's) I get something completely different. The UV's no longer line up with my old texture, nor do they line up with my new texture and new UV's. I only have one UVChannel in Blender, and didn't change any import/export settings (that I'm aware of).

Maybe it's just a dumb oversight? I hope? Any ideas friends?
