LQG of course breaks Lorentz symmetry near the Planck scale. The finite 
elements have reduced diffeomorphic symmetry, and which buries away any 
such problems. The numerical simulations you reference are a typical case 
of computer science, input variables in, output variable result. LQG has a 
hard renormalization UV cutoff that breaks the symmetry of the field.
