Obe the Illusionists' Helper Party - Where's the exploit??

Help, folks!

I swear that no more than a week ago, on this site, I read a detailed description of an exploit to get the training party out of the storehouse without having to use export/import or an external tool or leaving the game.

Now I cannot find that thread after dozens of search term variations, and even a scan of every thread title that is grayed because I have viewed it recently.

The description involved clustering the NPCs near the player and Obe, then dismissing them all, and denying their requests to rejoin. Then, I THINK, you either triggered Obe's teleport, or waited for him to get tired of playing around so he would trigger it himself. Paused, bespoke one of the NPCs, then allowed the teleport to complete. that left you with a remaining party member inside, whom you could use to speak to/join up the others and lead them outside to rejoin the avatar. I THINK.

Can any of y'all point me to the original post of the technique, or a subsequent description of it? I'd like to mess around with these guys a bit.
