alt Hacker NewsHeh. I remember similarly spending a few hours inside LambdaMOO. Successfully managed to clone myself, put myself in my clone’s pocket, and then put my clone in my own pocket and kind of broke room reversal. It was only later I discovered this was an intentional mechanic/bug that some designers that used to create very, very difficult puzzles.
Weird things happen when you give your MOO players a REPL in LISP land.
I once wrote an (Amylaar LPC) enemy who, if you attacked him and he was near death, would summon two comrades to fight for him.
Unfortunately, they're immediately hostile so you start attacking them too, and _they_ get near death and summon two comrades each, and so on. It turns into a Sorcerer's Apprentice scenario very quickly.
I managed to bring the MUD to a halt. An archwizard (not Yen Sid) had to instakill the enemies to avoid hitting their "near death" condition and creating more of them.
