If I sell my active ship, I am unable to see any other items that are equiped on another ship in my hangar. Selling items that are not on a given ship (goods, unequiped weapons, etc.) allow me to sell them properly.

Reproduction Steps
Buy a ship and make sure its active.
Go to the "Sell" screen in the Ship tab and sell your active ship.
Find a ship in your local cargo that has any items in its cargo bay or weapons equiped to a port.
If you select an equiped weapon/cell and sell it, you'll get the usual "This item is connected to your ship" alert. If you sell anyways nothing happens.
Likewise, if you try to sell something out of the cargo bay of one of your ships without having an active ship, nothing happens at all.

No errors appear in the errors log.

Thanks, MythOpus.

Huh, that bug's apparently been there for a long time. I fixed it for the next update.

Thanks again.

No problem :)
