Sounds similar to a problem my BP had when she had to choose between a half log and pangea hides, she would only ever stay in the Pangaea(despite it being on the hot-side of the tank.) I can recommend going and getting some of these hides as well if it is indeed a hide insecurity. They are also boatloads cheaper than any hide I have found at a pet store.
Also not as much of an expert but I try to help and gain more experience by reading all these posts and seeing solutions that worked.
