When using World Origin Rebasing, it is possible for the camera to offset itself from your starting location when exiting PIE. This will cause the next PIE session that starts at Current Camera Location to be at a random location on the map instead of the expected location.
Found in 4.16.2 and reproduced in 4.15.3.
Result: The location of the camera is offset upon exiting PIE, causing the next PIE session to begin at a different location than originally intended.
Expected: The camera location would not change after exiting PIE.
