I removed the whole family after playing a new group of Sims I created just for the Sulani experience. For some odd reason the whole family had a grudge or something against the six new Sims I had made. They went out of their way to make life miserable for my Sims, hated my pets and caused random arguments and fights with the male Sims. Whenever my Sims took their dogs for a walk someone from the Island family went out of their way to scold the dog, and for no reason since my Sims always cleaned up after pets. Maybe this family was glitched or something in my game, which would explain their dislike for non-island born Sims. Duane acted as if he hated the whole world except when it came to helping himself to everything in my Sim homes on the rare occasion when he was invited inside. I tried socializing with them, but after a few Sim weeks I realized there was no way that family was ever going to accept my Sims living in Sulani, and moved the Keoloha family into the witness protection program.
