I think it's two problems: it's a new type of bedding, and the hide is too big.
When I first switched Ryuu from paper to cypress mulch/coco bark, he seemed to play "the floor is lava" for a few days. I put in strips of paper laying on top, and each day took one piece out. By the end of the week, he was all over the place like he had been before.
The hide is also too big. They like enclosed hides with one opening, and that they can feel touching them on most sides when they curl up. Those half log hides are next to useless in my opinion. You can cut a hole in a little cardboard box and just replace it when it gets dirty.
