You'll have to forgive the PCs. I think sometimes they don't know when they're killing an NPC orphan or a player orphan. I'm pretty sure this is an intentional, hilarious feature.
For instance:
[ DRS ]: twisties asks, "seems ive been out of it. wtf is with these orphans
in the player list?"
[ DRS ]: Kano says, "newbies start out as orphans now; orphan players can't
gain IP and are basically meant for working out how to play the game"
[ DRS ]: Kano says, "like a tutorial level"
[ DRS ]: twisties says, "oh shit... That would explain why those orphans in
the cellar were harder to fucken kill"
[ DRS ]: Kano says, "ahahaha"
[ DRS ]: twisties says, "and why one was saying "IM NOT RABID""
I can hang around you and make sure no PCs try to mess with you, if you like.
Anyone, feel free to PM me with questions while I'm on, with 'Julian Huzzah!
Yeah, they take a lot of time to get used to, a lot like ASCII roguelikes. Sadly, the experiences didn't overlap for me, and each took a long time.
EDIT: If I don't respond, spam the hell out of me. Sometimes it gets lost in the information flow, or I'm AFK.
