Hi,
We've just been playing the side mission "Friends of Old", but it ended rather badly. The imperial player had managed to kill one of the rebels, and we revealed one of the markers as an Imperial Officer.
A hero then approached the corner of the map and successfully flipped the token there, rescuing a Rebel. However, the token also caused a squad of stormtroopers to spawn. The Imperial Player confirmed that the map places an Imperial spawn point right next to the rebel token! So the Stormtroopers appeared right next to the rebel, the Hero player's turn ended, then the newly deployed troopers immediately activated to shoot him into jam (including his extra health from the threat level). Imperial player wins on a bum note and Rebel players throw their cards on the table in frustration.
So is this a glitch in the mission? If that particular token is chosen as the one that triggers a Stormtrooper spawn, there seems to be very little the players can do other than surrounding the token before activating it - but they'd have no way of knowing to do that given that they don't know what the tokens do.
