So I returned to the game fairly recently and was invited to a new corp 89 jumps from where I was. I no longer had access to my old corps citadel (they merged with another corp) so after jumping I sent my assets into safety so I could get them out. They are now 45 jumps away. This is far to far for me to go get them but as they are safety wrapped I can’t put them on a contract which means I cannot get them shipped to me nor can I sell them off.
You need to fly to the station where they have been delivered and unwrap them. At that point, you can contract Back Frog or a competitor to move them.
Depending on your current location they can deliver them to you or to a market hub where you can re-contract to your corporation jump freighter service.
No remote option. Find a shortcut with wormholes / Thera, and do the trip when the effective distance is shorter. Also 45j in a fast ceptor will take 30min maybe.
