Basically I can't get warm from my fire place. And neither can any of my thermal stones. There is some heat coming from the fire. Looking at the color of the thermal stones they appear to be 25-40 degrees (wiki), but the fireplace should be 180+degrees (wiki). I have relogged several times and the thermal stones won't get any warmer during the day.
