Be ready to say "Yes, but...". Lots of times, the players will try to use rules in new and interesting ways, or manipulate a plot or situation to their advantage. Heck, its part of the fun. This is where "Yes, but..." becomes your best friend. "Hey, can we hijack a Lambda shuttle?" "Yes, but theres doubtless going to be tracking gear on the shuttle for the Imperials to locate it. And since its definitely Imperial, you may not find anyone who would want to buy the thing."
Or, you can use “Yes, and …”. And the part after the “and” could be something you decide to keep to yourself. Feel free to smile at the players while you do it, if you like. They don’t have to know what you have planned thanks to this sudden boon that they have given you.
So, the Lambda shuttle does have tracking gear on it, but you don’t mention that to the players unless they specifically ask/search for it. And maybe they find the first and second pieces of tracking gear, but not the third or fourth.
So, everyone knows that it’s an Imperial ship, and the players later discover that no one wants to buy it. And every time they approach someone to see if they want to buy it, that person ends up dead — or just “disappeared”.
Or, maybe you don’t smile. Practice your poker face, and just go with it when they want to derail the adventure, and see just how much trouble they can get themselves into.
Or not.
The choice is entirely up to you.
