Got right to the end of this mission, Q's gambit. Destroyed the Borg devices in the final room and then got killed by the Borg Boss. After i respawned I ran back to the final room again, but there were no borg to be seen anywhere. This is obviously a bug as the enemy should still be there so I can try and complete the mission. As it is I am stuck right at the end of it needing to defeat the borg boss who is nowhere to be seen!
