The cards are always the same, I've never accidentally somewhere once seen an object, thus can not be a replay value with new experiences in this direction.
Posted the companion secure a zone and work there are only visible to you tearing into another zone. After returning these disappeared (no matter how long you've been away). This problem also have other players and a solution (patch) there is not.
A great pity, without these two knockout points it could be a nice game, but as it is, unfortunately unplayable.
