1. Yes, if you are (For example) Allied with the Liberty Rouges, but hostile with the Xenos, and you go to rochester Base, both factions will attack you.
2. This is a well-known bug. Personally, I don't care what it's called ,if it comes with good loot

Doctor: I know. And nothing short of a Freelancer Sequel will cure you completely. But I can suscribe Homeworld 2. A half hour a day, and odds are you could lead a normal life.

i still dont get the 1st one. Next poster try to answer this example. If i am allied with the hackers, and the outcast ( hostile ) appear, will the hackers attack me?

As far as I can tell, yes they will. Think of it this way, as soon as the Outcasts show up, they'll start shooting at you, because you're an enemy. To defend yourself, you woudl shoot back. Now the Hackers see you shooting at one of their allies, so they're going to help them.

Trent: It's not the time, it's the sides that keep changing.

to shadwofire rouges ans senos are hostil with each other and the rochester is a junkers base and the xenos hates junkers.........
