What worked for me was this: Target a Citizen of Newport. Attack the citizen and when it gets below 50% and you see the proc go off spam the belt clicky. They normaly just say a text of "What? ....." and then they stop attacking. From what I saw if you keep attacking ater you try and enslave with the collar they dont port away but rather they stay on site and keep attacking, even though they are enslaved.
Example: I got the citizen in Oggok, but I di not stop attacking it. I didnt get the normal message but I left at that point. When I arrived in Erimal the NPC had been enslaved and all was well. Just make sure you are onnly trying this on a Citizen of X, with X being the city you are in, not a named NPC but specificly a citizen of that town.
Hope this helps.
