In this talk, I will discuss Yangian symmetry for planar twist-deformed N=4 gauge theory including the formulation as a symmetry of the action. I will also discuss Yangian symmetry in the singular limit leading to the bi-scalar fishnet model. Here, I will argue that integrability is likely lost as soon as graphs with octagon loops contribute.
