If he's feeding for you, I don't think you should worry just yet. My baby ball stayed curled up under his log for a couple of nights when I switched things around in his enclosure, so a move might take him a few more days, even weeks. Just keep track of his feeding habits. A happy snake is a feeding snake!
OH! I almost forgot, you should bump up your warm side to around 90, and only keep the humidity that high when he's in shed. Ideally you want to stay at the 50-60% range. Hope this helps!
