Description
The ground state for type A2n(2)+ should be based on \Lambda_n rather than \Lambda_0 due to the equivalence with type A2n(2). Since this is based on \Lambda_0, we have:
sage: K = crystals.KirillovReshetikhin(CartanType(['A',6,2]).dual(), 1,1) sage: T = tensor([K,K,K]) sage: hw = [x for x in T if x.is_highest_weight([1,2,3])] sage: for elt in hw: ....: elt.energy_function() ....: elt.energy_function('definition') ....: print "" 0 0 1 2 2 2 1 1 2 3 2 3 1 1

Looks good! For A_{2n}{(2)} dual there was indeed a bug in the path to the ground state beforehand.
