Most of my snakes dig around. My BRB and Bloods were notorious for destroying they're nicely covered enclosures. They'd dig up all the plants and move everything. I ended up just putting them on newspaper because of it. My Ball will at times dig around but it's mostly good so she's still on substrate. My Cen Am Boa actually burrows and is completely under the substrate 95% of the time. I wouldn't call that normal but I don't worry about it. I know the numbers are good and the enclosure is secure. So I let the snake do as it pleases.
As for probes this is how I do mine for my RHP.

As for your snake and now seeing your setup, I would add more moss to the hides. Make them as tight as possible. You might also want to turn the openings inward so they don't look out. A huge needs to make the snake feel secure. If the door is opened to basically a window that's not going to give them that. Most all my hides are turned in our even backwards, it at least a angle.
Then relax. If your numbers are good you are worrying over nothing. You may actually be causing it changing things and constantly getting involved. Maybe not.... But maybe.
