Notable Star Relocation

Notable Star Relocation is an anomaly where stars found in certain levels are drastically changed in location and/or the circumstances for spawning it. These often have vastly different goals than the original, such as shifting from fighting a boss to finding the star somewhere else in the level. This anomaly appears similar in nature to Dynamic Level Rearrangement, which also commonly appears alongside Notable Star Relocation, though if it is actually a part of Dynamic Level Rearrangement or a separate anomaly is unclear. It is believed to most commonly recreate stars from earlier builds of Super Mario 64, though can deviate from this pattern.

Examples
Below is a list of examples of Notable Star Relocation, what star they replaced, what the new goal was, and the course the example can be found in.

Theorizing
It is believed that Notable Star Relocation is the result of the Personalization A.I. recreating stars from early builds of Super Mario 64, while also creating entirely new stars, possibly as a malfunction. Why exactly this is done is unknown, though it is likely a result of Dynamic Level Rearrangement and the AI personalizing the game to the player.
