I bought the Armitage class ship from the c-store, I don't own the Thunderchild, the Oslo, the Akira and the Zephyr, yet I should be able to customize my ship using the pieces of 4 ships (Armitage, Akira, Zephyr and Oslo), but this doesn't happen. (On the contrary, I bought a Regent too, and i'm able to customize it using the Sovereign, The Noble and the Majestic). When I try to customize my Armitage, I do the modifications (without using the Thunderchild pieces), then when I click the "purchase" button, I get the message "You have already this item in your inventory" and I can't go on. I suppose that "item" means the Armitage. I have this problem with my two fed characters: Fox@Gisors and Franz@Gisors. Please help me!
