I'm sincerely worried (and sorry) to see more and more people coming with the same problem... It has been 16 hours (probably more) since I discovered my main like this and tried to log in. I'm pretty sure I disconnected in the middle of Eulmore, the last thing I did was running the last NieR Raid or some expert roulette. No idea what could have caused this to happen.

Good luck everyone, I guess we can only wait now.
