When the Tal Shiar Adapted Destroyer and Adapted Battle Cruiser first came out the bridge crew worked pretty much like it was supposed to; your BOffs appeared at various locations on the bridge and if you didn't have enough BOffs then random Romulan NPCs would appear.
At some point after the release, something changed and now only the first officer appears on the bridge and all the other bridge stations are occupied by random Romulan NPCs instead of the player's BOffs.
Can one of the devs make this quick fix? I can't imagine it's that hard to have our BOffs appear on the bridge.
