Overall the tank looks nice. I do have two suggestions.

1. I like adding moss to my hides. During a shed you can make it damp and it will really help your sheds. It also helps the snake feel secure. I bring up security because of the hides you are using. The half logs are not that great for snakes because they have two large openings. What I like to do is stuff moss in the end pushed against the glass and then put another clump at the other opening. This will allow your snake to easily slither through the moss to hide inside and will make the snake feel more secure in the hide. This alone could help limit the roaming.

2. The hot hide sounds a bit warm. I keep my BP hotspot between 88-90. Nothing more is needed. Having the hotspot in the upper range leaves very little room for the temp to change and become a undesirable temp for you snake. I would drop it a bit. This to could help limit the roaming.

However, with those two suggestions they may work and they may not. It could be hunger or any other thing. All you can do is try a few things and see if it helps. In the end it may be nothing and you may just have a curious snake. Being a snake owner you will learn that many times our snakes seem to do things just to confuse us and make us worry.
