After you get the last artifact, and One Giant Leap starts, you will see Vladimir, Barrett, Sam, Andreja, and Cora all sandboxing within the Lodge's library. This makes some sense at this stage, as everyone is waiting in anticipation of your return from the Buried Temple. If you jump to the Unity and return though, they will all still be crowding the library for the rest of that playthrough.

Details

This is because MQ305_SandboxAtLodgePkg [PACK:001F0B88] is given to these characters while this quest is running. However, aside from excluding active companions and crew, there are no other conditions for this package to ever end. Strictly speaking, this is working as designed, but it doesn't make sense for them to all remain in the library for the rest of time.
