Last session, one of my players tried to reprogram a Combat Droid to have him as his master... I assigned a Hard difficulty and he did not pass the check, so the Droids were left with their restraining rods...
Still, I think now that allowing this to the players could potentially derail a campaign, as they could be reprogramming any droid that falls into their hands to follow them as their masters... How would you deal with this situation?
