Radiative Surface Rebuild Errors

Hello All,

I recently encountered a problem when applying a radiative surface (non-radiating surface specifically) boundary condition in Flow Simulation. I receive the Rebuild Error, "Cannot find bodies associated with this feature". The odd thing is I have another boundary condition (surface heat flux) applied at the exact same surface without error. I've been running the exact same simulations for several weeks now and have not encountered this problem before.

Any advice would be greatly appreciated!
