I haven't encountered any actual bugs in this EP, at least none that people talk about, but then again, I never hired a ranch hand. The only thing that annoys me is the rather long, noticeable delay whenever I tell a sim to interact with a horse. It often gets to a point where it seems like the sim is ignoring my order, then I tell them again, and suddenly the interaction queues up twice in a row. Sims also sometimes dismount the horse for no apparent reason and without an explanatory pop-up after I tell them to go for a ride.
