Please don't be offended by this but she is probably finally happy in her home. IMO she was probably out roaming all the time because she was stressed and couldn't thermoregulat because she didn't have a heat gradient to move between. Now she has what she needs she's happy to just stay in her hide in the temp that she wants to be in. Happy royals will spend a lot of the time hiding and not roaming about.
Again this is my opinion.
