I have been to every room and sideroom on malachor 5 opened every box and beaten every enemy.  Crescent, Prison etc on both sides of the central room.  For the life of me i cant figure out why the doors remain locked.  I hope i have just missed something and not a bug.  
  
     It wouldnt be the first time i have had to do a level over from a bug.  The first time i fought the Twin Suns i turned on my stealth and they started fighting each other until one died.  Then i couldnt target the second twin and the door to the cantina wouldnt unlock. 
  
     Overall a good game but seems to lack the polish of the first and a lack of anything truly new.
