Oh, I'm so sorry to hear that
I'm sorry to have to welcome you to Frog Forum after the obvious loss of a frog.
Unfortunately, desiccation occurs very quickly if you are unable to recover them really fast.
That's sad.

D auratus are very shy - they will hide a lot , especially if they are not adjusted to a new environment.
They are easily stressed and don't like their stuff messed with .

Good luck with the others
Lynn
