[DynaBlue]

I've just found out about Starfury and have been playing it for about 2 days. Game is like crack with a keyboard!

I've gotten a few missions done for my contact at Freeport and he sent me to Pakulon to take out all Amankrie (sp?) ships I find there. Well, I found LOTS and they were all gonna whup up on my Destroyer I so I boogied out and figured I'd come back later. Now, with the exception of once finding a freighter, I can't find ANY of their ships in the system. Been back many times, upgraded my sensors out to the best I can find, cruised the block a few times but still nothing.

Any suggestions? Do I just need to keep leaving and reentering the system to refresh the ships present?

Thanks!
