So I logged out last night with all of my hotbars and gearsets in the same position they've been for months.
I log in this morning, and all of my hotbars and gearsets have been reset.
I only play on one computer and when I logged out, it was fine. I get that I'll have to probably reset EVERYTHING but PLEASE SQUARE ENIX, DON'T LET THIS HAPPEN AGAIN.
Also no I don't have a backup because I didn't anticipate this happening >.<
