mob/dead/observer fails to GC

[2022-10-09T19:05:16] GC: -- [0x2100000d] | /mob/dead/observer was unable to be GC'd --

Steps to reproduce the problem:
Send a ghost back to the lobby

Extra information:
Very likely related to innate byond stuff, due to the fact the GC finder can't get a ref

[chuga-git]

Still an issue. This can be replicated by reincarnating your ghost from the player panel as an observer.
