As I created my custom backround (panorama) with a resourcepack, I noticed BoP overwrites the vanilla one. Made an assets folder for "biomesoplenty" and had the texture root that goes "textures" -> "gui" -> "title" -> "backround", however, it didn't apply when I put my 6 custom panoramas in.
Proof
Does anyone know what could cause this issue? Or did I derp?

Thanks in advance!

Just saw that a config option got added - awesome!
