If you set the bomb on the upper level of Hathor mine, click to use the trapdoor and the timing occurs so that your character reaches the trapdoor and moves to the lower level while the cutscene of water flowing down the hole plays, the camera will not return to where your character actually is, but to the upper level. If you use the trapdoor while the bomb is counting down, the camera will return to your character properly after the cutscene plays. Admittedly, this is a minor nuisance since you can still re-center the camera onto your character by double-clicking on your character portrait.
