I have tried searching for answer to this issue and found nothing so I hope someone can help.

I have just spoken to ES-05 regarding the re-activation of M4-78, however, after leaving the Archon 1 Behaviour Core and reaching the 4th Recharge Station the door leading to RS 3 would not open.

I went back to ES-05 and went through all dialogue options incase I missed something, went back out and the door still would not open. The 2 Battle Droids had nothing to say apart from 'You may not pass' or somesuch but then the door opened. I entered the small connecting corridor between RS4 and 3 but the door to RS3 will not open and neither will the door to RS4 so now I am stuck in between both areas and can not progress. The Escort Droids when activated just give the message that they will be usable once I return to the Central Zone but I can not get there.

I have tried reloading the manual save I made when entering the area leading up to ES-05, the auto-save when I entered the Archon 1 Behaviour Core and still the same issue. I can not progress any further and it's really, really starting to annoy me especially if I've just lost the 28 hours worth of progress on this character. Anyone know of a fix?
