I'm not sure I really understand. If you mean when the lifetime sub ends, it doesn't end until the game servers are powered down and STO ends. If you mean the lifetime sub sale, I think it ends February 4th at 10am PST.
Hmm...I see that too. It looks like it's not quite ready. Maybe they released it early by accident?
Seems the bridges are on Tribble, and will let you "preview" them (not sure if you can actually buy them on tribble, and I wouldn't really recommend it either). Also, there's only 3, so the "four" is probably a typo.
I bought them for the listed 96CP. Only 3 show up in the ship customizer so it is more than likely a typo.
