I've played Runescape since about 2006/2007 but quit right after the citadel update. I have come back after about 5 years because I heard about the Oldschool Runescape fork. I am aware it resets your character for OSRS, but that should not be the case for RS3. I was forced to create a new username and it reset my whole character. I wasn't hacked, it's just that everything is reset. Completely fresh character.
I have checked with all my emails and made sure that there was only one account associated with each email address. There is only one. Just to stress this - I am in complete control of my accounts and always have been, this is not a problem with account security.
I am planning on playing OSRS, but i'll be damned if i'm not getting my character back if i'm able to.
Was there an update that messed with the accounts/usernames/whatever? Is there a way to recover my old username/character?
I'm really not sure what to do next. I can supply any other information if I need to.
