I have finished Mina and Jonathan, fully upgraded my new ship, and finished Ben's final 3 contracts. After collecting pass tickets from all that, I only have 4665 tickets, leaving us 135 short of the 4800 needed to finish.
So, where are the other 135 tickets hiding? I guess we could do Mina all over again, but that only nets another 120, bringing us to 4785, still short of 4800. Doing Jonathan again thru contract 4 gets us another 20, but this approach seems pretty weird.
I feel like I've missed something.
