So the next day I loaded my game to find I had been returned to the area when you have to align those rings in the laser section.
Then after finishing the two rings and almost exiting to the last room, the game starts responding and I get the mini shortcut in which Juno tells me what to do with the rings. And I'm returned to the area before the first ring. Again.
(and then later a few purge troopers killed me after I got the black crystal yaaay)
