I have a problem with the Dangerous Minds part of the main quest,

I have rescued Valentine, killed Kellogg and retrieved the brain augmenter but when I go to memory den, I cant proceed as the memory loungers are all piled up at the front of the memory den blocking access to the exit.

As a result of this I cant progress.

I have tried waiting for 24 hours and have reloaded multiple times before entering the memory den but its just stacked up at the entrance...

I am on the XBox One version.

Any plans for fixing this glitch?
