it seems they fixed it so you can't have more than 1 acc logged into a lobby, so you can't quickly login to the same world anymore.
is there any other methods out there?
Real knowledge is to know the extent of one's ignorance.
I can get multiple accounts into the lobby, the same as always. Logging in quickly with 2 or more accounts into the same world is working fine for me too.
When you try to enter the lobby with a second account, what exactly does it say?
