If you haven't played Guild Wars 2 today and aren't planning to log in until tonight, you won't notice anything different. However, those who played in the hours just after the latest GW2 udpate went live will have any progress gained during their game session rolled back after a seriuos bug without any solution presented itself.
There’s a bug in today’s release that can cause soulbound items in an inventory bag other than your first bag to become soulbound to a different character on your account. We can fix the bug with no damage done, except we can’t straightforwardly fix it if you’ve moved one of those incorrectly soulbound items into bank storage. We’ll have to work on a solution for characters in that state. To prevent additional players from getting into this state, we’re going to shut down the game servers until we can fix this bug. We apologize for this inconvenience.
However, a fix was not to be found as hoped. Instead, servers are down and will be until a roll back to pre-update status is achieved, likely sometime tonight.
This is an update to the situation where soulbound items have been incorrectly soulbound to the wrong characters. After further investigation we’ve determined that there is damage to almost all character records that were played this morning, not just to those who transferred soulbound items to or from a bank. To repair the damage, we will have to roll back the state of the game and characters to prior to this morning’s release.
No one wants to lose a play session’s progress. We apologize for this. I’m sure you’ll also have questions about exactly what a rollback means to you. The general answer is that everything about the game state, including things like trading post transactions, will be restored to how it was prior to this morning’s release. The only unusual case will be that if you purchased the game or purchased gems this morning, you’ll still get your purchase.
