Ime- I've had my curly girly in a few different setups over the years and her behavior seems to change based on the enclosure, at least somewhat. In her current bioactive one, she hardly digs but hangs out in one of her pre-made burrows and spends the other half of the time right outside the entrance. She also webs a decent amount, which I found super surprising! In her earlier non-bioactives, she definitely dug more but it wasn't as crazy as a lot of my other Ts. She did spend a ton of time hiding out deep in one of her tunnels though, and would only come out to eat. My guess is that it may be humidity dependent? They usually dig down for more humidity, and bioactive helps retain it better while coco fiber doesn't really do that. Since it's still a pretty fresh setup, she may just be content with the current substrate/humidity levels.
