private server

Start with macros.txt and reproduce the talknpc 44 167 c r3 c n sequence on the named private server, checking the repeated NPC Healer#Askald output. Compare the conversation flow with the talknpc entry point; done means the macro no longer repeats “Done talking” and does not stop afterward.
