Hello,
In the Cortez System I wanted to sell two DULZIANS to the player DareDuck.
When I reached my destination the Internet cable became lose and I lost connection.
When I reconnected I was at the last station i was before and the two DULZIANs were gone.
you might be best served to have a screenshot to show you had them. I have had issues like this in the past and if you can't document you had them, you might have a harder chance to get them back. I know its a pain in hindsight, but SS 's go a long way in these cases.
Good luck mate. and I'd maybe try to PM Cannon, as he is a GOD with this kind of problem.
