I am advising other players that purchasing any Arx and pre-built ships using your Frontier account does not get transferred to your linked account e.g. Steam account. All money spent there would be lost and not accredited to your game account. This has been my experience and heed caution before you end up wasting or losing money for non-deliverable items. Their instructions on how to claim the pre-builts ONLY works when you purchase the Arx and pre-builts in-game and NOT via the Frontier store. Shopper beware there.
