It was just the towel. I put the carpet back in and she's fine.

I used to use the aspen bedding but I find the carpet is easier to keep clean and easier to regulate the temp under the hide. I got the other carpet out from behind the dryer, which is good because she deposited urates last night right after I put the carpet back in so guess what? I get to change it and wash one again today! She's still easier to clean up after than my cat. And yes, I always wipe down the floor of the tank when I change carpets. I'm as concerned as you all are about keeping her environment as optimum as possible.

I don't use an actual UTH. I use a heating pad made for humans and I have a probe thermometer in the tank between the glass and the carpet. The tank is in my living room so I am constantly looking at the temps and humidity. If the hide starts to get too warm I pull the pad partway out so it can cool down. It usually runs around 90 in the summer and 85 in winter. If it gets up above 92 I pull it out a bit. Also, the tank is propped up so that there's about half an inch of air space between the pad and the tank bottom. My nephew had a UTH that shorted out and badly burned the belly of his BP. I think it's a wonder the snake survived. He did but has a long scar on his belly from the burn.

My humidity is provided by two washcloths that I wet, wring out and put on top of the cage top covered with plastic tub lids. I leave about 1/4 of the top open for air circulation. It's improvised to be sure but it keeps the humidity where it needs to be.

All in all for someone who wouldn't have chosen a snake for a pet, even though I had two as a kid, I'm enjoying having Kari and I'm committed to giving her the best life possible. She seems to be doing fine.
