We reexamine a recently proposed non-inflationary solution to the monopole problem, based on the possibility that spontaneously broken Grand-Unified symmetries do not get restored at high temperature. We go beyond leading order by studying the self-consistent one-loop equations o f the model. We find large next-to-leading corrections that reverse the lowest order results and cause symmetry restoration at high temperature
