texture changes when the camo block im using is placed under it

But it seems to be drawing this texture

Figure id add that

[Kamizzel]

I figured it out, it seems like the torchmaster lightsource's created by 'Feral Flare Lanterns' love to bug out framed block textures

[XFactHD]

I have an idea why this is happening (it's an issue with the ConnectedTexturesMod used by Chisel Modern). What is the position of the Feral Flare Lantern blocks causing these particular blocks to break?
