First, I am so glad that you found her and that she is okay! I called my husband in a panic one day because one of our ~500 gram snakes was nowhere to be found in his enclosure. Turns out he had somehow wedged himself behind the foam background. No idea how he managed to squeeze behind it.
Your ^ above statement about the RHP warping is concerning to me. You do have it controlled by a thermostat, right? An RHP should not warp with heat, because it shouldn't get hot enough to be affected like that.
