I have 2 accounts, which are "remembered on this computer" and I am unable to log into either of them. These technical issues have become all too frequent as of lately. And with no "apologies for the inconvenience" from the devs makes it a bit frustrating.
It would seem that the issue may have been tied to the launcher. If you had your login "remembered" on your PC, saving your username and password, this feature was reset. Your user name was still there, but you had to re-enter your password and check the box. To anyone who plays on console, please note in the replies if you had the same issue today, or if it was just tied to PC users.
Constantly getting hung up at validation. If I do get in, it boots me before I actually load into the world.
