Yeah, I wasn't expecting much from the ruins either. Evidence is really hard to come by from outdoor locations, I've noticed. If it's not the outside noises, it's a trick of the light, people just getting spooked, animals, or the fact that the departed have decided to pass on and a lot of residual stuff lingers (which makes it hard to get solid evidence). Lisheen was a pleasant surprise, but I definitely agree that the faerie ring had something to do with it.
