This was just posted on the official forums regarding Sasano. There is apparently a 50% chance it will permanently lock your character in game, i.e., you will not be able to log back in again until they fix it.
Quote:Greetings,
Thank you for reporting this concern. We understand that it's incredibly frustrating to be unable to access your characters during Early Access, and deeply apologize for this inconvenience.
We have confirmed this issue with the development team, and they are putting high priority on continuing to investigate how to resolve this for players.
At this time, it seems that the situation will require a resolution via the client itself (through updating the version). As such, we expect it to take more than several days to resolve this issue, including the time required to create the patch.
However, because this error is not caused by the corruption of local data or due to a PC issue, it is likely that re-installing the game will not resolve this issue.
Again, we deeply apologize for the inconvenience. We'd also like to note that if you continue to attempt to log into the game there is a chance you may be able to log in, so please try again after some time has passed.
