Just figured I’d pitch in on this: there are some weird things that happen when you allow your reputation to go all the way to 1 or -1.
For a reputation of 1, NPCs excuse your friendly fire and a few other things (the offset for this is in the Limit Breaking 101 under NPC behavior) - I personally look at this as a feature (which is why I found the offset for it, I wanted it on all friendly NPCs), but it’s behavior that you may not want, so adjust it accordingly if so.
As for -1 reputation, this seems to make all NPCs of that faction exclusively target you. While this doesn’t matter in vanilla FL (all NPCs prioritize players anyways), this is game-breaking if your mod is designed around NPCs shooting other NPCs as well as players. Again, it probably doesn’t matter, but just keep it in mind if it’s behavior you don’t want.
