In TSW3 there seems to be a glitch with the external camera where if you are on the external camera for a long period of time (I don't know exactly how long it has to be...maybe 5 or 10 minutes), you cannot return to the internal camera. When I press the R3 button to return to the driver's seat the camera does not switch. Instead it becomes like the free camera (it stays outside) where you see the train continue on but the camera stays still. You cannot move it anymore however I can still cycle back to all the external cameras (press R3 and right directional button). If I press the R3 button to go back to the internal camera view (and get this weird glitch described above) and press it again the game will crash. I'm playing on PS5 btw.
