I had something like that happen too. I was in a pinch in a temporary situation with one thermostat and two set ups. The emitter in the side with the probe went out, which then spiked the other side. When I went in the room, he was sort of waving at me, unlike he had ever done before, like a puppy at the window. "Hello! Idiot! Get over here!" He must think I ride the short bus!
