Trouble with conversations

Conversations - inserting reference lines correctly - counterintuitive but this is how:

1. Right-click the destination NPC line and click ‘Set Link Destination’, then
   
2. Right-click the PC line that should point there and select ‘Insert Link’.
   

The same text is inserted automatically cast in grey, to signify that it’s just a reference. If you change the dialog text of the original line, it will update all references that point to it.
