I just did a level one fractal run as an introduction to a new player; he was level 52. He was correctly upscaled for the first two fractals, (Ascalon, Uncategorised). However, for the third fractal (Cliffside) he was not upscaled at all. The poor guy had a terrible experience being one shotted and had no idea why until we noticed. He tried relogging to no avail. We completed the fractal and progressed to the final boss fractal (Molten Alliance), whereby he was once again properly upscaled.
