Question About Subscription Expiring and Items

[FlaresPK]

I've heard that if your account expires, that when you reupgrade your account, your account resets when you next log on kingdoms. Is this true? Because when the first account that expired for me (Flares) expired, I came back on one of the free weekends and extracted the Ruggili's Plate (Which is the main item I am concerned about) from him, and gave it to my current account (FlaresPK). However... people tell me it's changed since then... is this true, because if it is, I'd hate to lose Ruggili's Plate...
