I bought a couple of items off CP exchange, now it appears the seller has loaded then into crates and loaded them on a c-3. no coords for me to pick up from, how do I resolve this?
Uj, I am guessing you mean you bought some items from centerpoint market - getting items from the CP exchange would just spawn them at your location.
Have you talked with the seller as to why he did that/where they are? When selling items people generally make sure they are on a secure location so others cannot pick them up, and then give access to the buyer.
Given that he does not seem to have a CPM profile - I'm guessing he bought them off the NPC market.
In which case the items may have been lying on an open location, and anyone could have walked in and simply taken them.
Finding the owner of the ship (probably the traders lounge) is then likely the best bet, unless the person have actually picked up any of it, and become assigned as carrier.
