Abstract: Theories of low-energy Lorentz violation by a fixed-norm “aether” vector field with two-derivative kinetic terms have a globally bounded Hamiltonian and are perturbatively stable only if the vector is timelike and the kinetic term in the action takes the form of a sigma model.

That does not mean there is none, only that critical strings are under much better control, especially when considered non-perturbatively.

Count Iblis, the point is that if you have a renormalizable theory you can to some degree expect to be able to define it perturbatively, since order by order nothing undefined happens.

The question which do and which do not, and whether one can do it perturbatively or not, are very interesting open issues, not a lot is known about them currently. best,

It's silly because a lattice formulation is just one among infinitely many ways to define physics of a field theory non-perturbatively.
