We present a method for mending strategies for GR(1) specifications. Given the addition or removal of edges from the game graph describing a problem (essentially transition rules in a GR(1) specification), we apply a \mu-calculus formula to a neighborhood of states to obtain a "local strategy" that navigates around the invalidated parts of an original synthesized strategy. Our method may thus avoid global re-synthesis while recovering correctness with respect to the new specification. We illustrate the results both in simulation and on physical hardware for a planar robot surveillance task.
