Zoose did this for a while in the 20g tank I had him in. The hiding spot wasn't the problem, but the temp there was. His new "hidey-bowl" was much cooler than should have been comfortable, but he liked the security too much to go where it was warmer. As a result of not moving the bowl, I'm into the second week of dealing with his regurge.
So, I'd say, if all else is good in his new favorite spot (humidity, temp), he's probably okay.
