It's possible to have a POI get stuck and become unusable unless the entire level is reset. If you set a POI to appear at a trigger and respawn on a checkpoint, then activate the trigger that makes it appear and respawn... It stays where it is but cannot be activated. The expected behavior would be for it to disappear and reappear on trigger again, but rather it becomes unusable forever.

Nevermind: Apparently it happens when there's something on top of where it should respawn. Like a checkpoint or dragon head shot.

It can be usable again if you respawn multiple times until it's working. A bit annoying, yes, but wouldn't be the only place in the game where something like "respawn multiple times to be sure" has been used.
