Hoping Customer Support can help
Edit: The official Blue response, and the strange anti-consumer coterie of extremely online forum poster hangers-on, is that the trading post model viewer is entirely useless and there’s no guarantee that what you purchase is something you’ll still have even 2 months later: “Things can change. I’m sorry if that is so distressing to you”
Just roll the dice each time and hope what you buy sticks, I guess.
