What are you gonna do?

Im going to finally finish all of the archive missions.

I think those were all server-side and are lost forever. I hope I'm wrong about that.

This collection is missing 16 archive critical missions and about 30% of all contact missions.

I don't this is the case actually, this is something ussually done client side (Note whenever the devs made a fix to a mission, such as a typo, they updated everyone's client).

However, it would still be a question for someone who's looked in depth at the client code.
