Do you have lots of plastic plants for cover. Not sure about ATBs but i know with GTPs, if they ground themselves, it either means the cage is too hot, they are sick, they are pregnant, they dont like the perches or dont feel secure on them. Make sure you have lots of plastic plants or live plants so the snakes feel secure. But like i said, i dont know too much about ATBs so i cant really help with temps and stuff. I will say though, i would let the humidity drop to around 50% and dry out a little, then spike it back up with a misting on the substrate. I know with GTPs, if they are kept constantly wet or too humid, they can develop water blisters on their skin. With them, you want to spike the humdity and then let it drop back down to around 40-50%, then spike it back up and rinse and repeat.
