Just got onto Guild Wars 2 this morning to find out my password was not valid. So i changed my password and went into my account to find somebody had come on and made a new character, so i deleted it. I opened up my main character to find myself moved into the trading post at Divinity’s Reach with all my money gone.
Faramir, you need to write a ticket to Customer Support, if you want to have a rollback. Check this page for more information about it; we are offering one per account. Also, as Squall Leonhart says, would be even better to add the authenticator system for an extra layer of security.
