I'm the opposite. I could never understand how you could have Lorentz invariance if you discretize spacetime. It might emerge as an approximate symmetry at larger scales, when individual violations average out because of the randomness of the lattice.

I see QLG mostly as a regularization scheme that gets rid of infinities by providing a short-distance cutoff. But this cutoff cannot be Lorentz invariant, as Sabine points out. I can't see a way out of it.
