I have recently completed "My Kind of Town," and the residents of Primm won't leave the casino. Johnson Nash refuses to trade unless he is home, eliminating him as a trader. I have yet to activate ED-E, and the wiki doesn't have any other possible fixes. Nor does using a prior sace help. Does anyone have and advice for this? I'm on a console.

Sadly, this issue's been around since one of the first patches, and it was never fixed. IIRC once you finish MKoT, every resident of Primm stays hold up in the Vikki and Vance. It's kind of sad since it worked just fine in the base game

Its not bugged in my patched and DLCed game.
