I was on act 3 jungle ruins and when I tried to enter a new area (I thick it was some sort of cave) it kick me out to the login screen, now each time to I try to enter again after selecting the character it kick me again "an unexpected disconnection occurred" please help

The patch broke the game.

Getting the same "Unexpected disconnection error"

kind of it got fixed after creating another character and reaching the town into the next area. but now I'm afraid of entering "the venom crypts" and get the same bug
