I have the same problem - only on my second rotation, but several of the chests are already visually open, and are not interactable. The achievement is visible in the achievements pane, I'm able to track it, and the chests I'm having problems with show as not yet completed. But I did the chests in a somewhat arbitrary order the first time through, so I can't say how those which I can/can't open correlate to any past activity. @Doghouse.1562 said: I have the same problem - only on my second rotation, but several of the chests are already visually open, and are not interactable.
