To be more clear when using the mahou tsukai mod and it's ability called shared vision, or mental displacement, my camera briefly flashes to where it should be before taking me back to the normal first person point of view I should have. Same goes for the betweenlands mod, when trying to go into third person in the weedwood boat your camera briefly flashes where it should be before going back to the normal first person view. If it needs more clarification I could try to make a video.
