Chains PBR textures don't load and start to emit light in certain locations.

Chains have an unusual lighting issue depending on the blocks around them and their location while ray traced lighting is on. They begin to incorrectly load their PBR textures and start to emit light, but only in certain locations. Unfortunately I haven't been able to find an exact method to reproduce this issue but I will be on the lookout for when it occurs to myself again.
