If you side with Gizmo and take out Killian for bottle caps, most of the people in Junktown try to kill you. Even the gamblers in Gizmo's casino try to take you out. And if you go to Saul's bar when it's closed, you get attacked by an invisible Trish. All this is from a game with Fallout Fixt. I thought Fallout Fixt fixes all bugs.

The first doesn't sound quite like a bug: you've killed a guy the town people like on behalf of a guy they don't like, and the gamblers ae town people.
The invisible Trish rings a bell, I think I've come across it before. Fallout Fixt fixes most bugs -especially the gamebreaking ones-, just not quite all.

Yeah but are they that loyal to Killian and brave enough to try to avenge him? They don't even have weapons. If such a thing happened in real life, they would run to their homes, lock the doors, close the windows and hide.
