In Sulani, my dogs walk away into the rocks. Then they got stuck there.

My Sims live in the Tangled Flat lot, and from there, suddenly, my dogs start walking away. This is my second dog, who is doing this. My Sims also freeze in one place. None of the actions work. All the dogs are going towards the same spot, it is the middle of the mountain on the edge of the water, near the small decorative set piece bamboo cabin with a very high roof.
