Ailith introduction animation in the Monastery doesn't end/disappear (Bug Report #2,947,495,021)

First time I went to the Monastery of the Keepers in the endgame, I spoke to Ailith, and after she walked off-screen, I went over to find where she normally stands next to the Genesis Tree... As well as a walking copy of her that was rooted in place, continuously stuck in her walking animation.

This "clone" appeared to have been the original Ailith that greeted me at the entrance, having failed to despawn when the "permanent" one next to the Genesis tree appeared. Worth noting that this "clone" was not interactable in any form, and had no collision whatsoever.

This "clone" persisted indefinitely and never disappeared for the remainder of this instance's lifetime. All future instances of the Monastery of the Keepers opened instead operated as normal, with only the permanent, standing copy of Ailith present.

• Bug Report ID: #2,947,495,021.
  
  
• Reproduction: Should be trivial: enter the Monastery for the first time, talk to Ailith so she starts walking towards the Genesis Tree. Then get her off-screen. I'd gone all the way to the left side of the Monastery, so it might've pushed her entity onto/through a line for de-loading/"sleeping" it before she reached the permanent despawn point.
  
  
• Screenshot: Attached is a screenshot showing the two Ailiths present. The one without the quest prompt icon over her is the "clone" that was stuck in place.
