duped a few more ended up at 70 and got bored. but yeah i followed a youtube video saying dont pick up stuff, blahblahblah, and i was able to dupe 60 of them. pick them up, and continue duping...
Confirmed, HOWEVER, when I got back to the room I did a few more nodes and then looted those up, after which they stopped respawning.
edit: As a side note, it may have been caused by the reappearance of the door over the maintenance vent. I removed it prior to starting the duping like the video showed, however I just noticed it is now back in front of the vent.
