@TomI emailed Tyler from tortoise supply and he wasn't too happy. He said my problem is the enclosed chamber and that they are death traps which is why he doesn't use them. I know I caused his dehydration because I didn't check floor temp that one night.
What I'm really confused about his that I've followed everyone's advice and care sheets and he was doing well and then suddenly after the high temp he immediately declined.
He said he would make an exception and replace with a new tort if I pay shipping, but there would be no guarantee if I kept it in a closed chamber.
I'm heartbroken and I don't know what to do.
