Main quest gets a "completed" chackmark, but gets stuck

Looks like whatever has updated today fully broke the game. Now main quest can’t progress, Mad King’s Breach getting a “completed” mark, but getting stuck (imgur. com/a/HQh49OE - remove the space after the dot. It’s crazy that screenshots aren’t supported by the forum even as links).
Mad King’s Breach is the quest my 2nd character was on that I just went through to no avail.
Greeting Cards also can’t be sent: “Confirm” doesn’t do anything when pressed.

Sending Brumaltine’s cards…

  • You can only send cards to players that are on your Friends list
  • You can only send one card, per day, to each of them

If you attempt to send a card to someone you’ve already sent a card to that day, the confirm button will not function, as you cannot send multiple cards to the same recipient in the same day. This is not a bug.

Thanks!
I did the dungeon again and now the quest worked. The bug was probably caused by massive lags that were happening at the time.
The post cards are still not working. I have 1 scroll item that’s used for sending them and I have 3 people in friends list (all befriended by my main char). I only sent a card to one of them by my main. I’ll see if cards too start working at some point.
