I think this is a bug? I read that this apparently happened to some people with some previous expedition reward ships, but it's the first I've seen it. Steam version.
When I tried to claim the ship, my only claim option was to buy it for 1400 nanites. I hadn't that much left, I basically spent all my nanites on minotaur AI and upgrades (because fuck having to fight yourself in this game). Since I couldn't buy, I had a warning I would not be able to claim it later, and even though I cancelled, while I was trying to farm for nanites that game switched to normal save and I couldn't claim anymore (even from Anomaly).
I've confirmed in another save that the reward is available, but since I don't have that much nanites, I haven't try claiming yet, just in case it got eaten up again.
To keep up with the worst reasons for which people can hunt fossils, on top of selling them in auctions for rich assholes, now you'll be able to grind them into a powder and sell them as medicinal remedies.
