Weird/creepy messages in the console

[f4IIIIs98]

I noticed that sometimes there are strange messages in the console when I open it, a recent example is "Nathan is in no man's land, returning them..." it creeps me out and I don't know why/when it popped up.

Update, also got the same message with Manya instead of Nathan. These are the names of npcs in Megaton so there may be a connection there, but still creepy

Sorry for the very late reply, but I was away from the site for months due to health problems and other RL issues.

If I remember correctly, Megaton NPC's can vanish and be teleported to an empty area (this is a bug that exists in normal FO3 too). I think those messages mean that the NPC bugged and was teleported to this empty area, but it was fixed by whatever plugin teleports them back to Megaton.
