Using debug to teleport myself long distances makes NPCs disappear

[AmarinReyny]

Describe the bug

So, after recruiting another NPC follower to bring back to camp, and finding out about the debug option that lets me take control of NPCs, I decided to kill two birds with one stone by taking over my new follower and teleporting them back to my faction camp, before going back to my primary character and doing the same thing with them. After I did so, I realized that none of the other followers I had were in the spots where they were before. In fact, they weren't anywhere at all. The overmap showed that they were allegedly still in that same overmap tile, but they just... weren't there. I even checked through debug to try to see where they were, by using the debug interface to edit their stats, and they weren't listed in the reality bubble at all - nor did they display under the list of existing creatures on the "game state" thing. Fortunately, the autosave didn't activate by that point, so I was able to recover my previous followers, but I knew I had to be careful going forward. As such, I decided to do some testing, and I pretty much found out that using long-range debug teleportation to enter a place where the NPCs would be in the reality bubble caused the NPCs to disappear.

Weirdly enough, using the short-range teleport to travel the same distance doesn't seem to have this problem.

Steps To Reproduce

1. Get an NPC follower.
2. Walk away until they're not in your reality bubble.
3. Use long-range debug teleportation until they're in your reality bubble again.

Expected behavior

I expect my NPC followers to continue to exist after I teleport.

Additional context

Only after I started typing this did I realize that I haven't tested what happens when I long-range debug teleportation to move around within the same reality bubble. I'll do that once I'm back at my "gaming" "laptop."

Debug is debug.

Debug is debug.

I mean... fair, but... I just kinda figured that the bug should be reported, not just in hopes that it might be fixed, but also so that other people who use debug a lot - not just for cheating, but also for, you know, actual debugging and testing things - can avoid any nasty surprises.
