No option for additional recruitment in dungeon when someone leaves

Was running The Lost City of Amdapor when our tank disconnected. Roughly 30 seconds after he disconnected, he was removed from the party. Usually when someone disconnects, you have to wait a few minutes before you have an option to remove them, but this guy was removed from the party automatically after 30 seconds or so. And the odd thing was, no one in the party got a popup for additional recruitment. The Duty Finder window did not have an option to recruit new members. WE were stuck in the dungeon tankless, and we had no choice but to abandon the dungeon.

same happen durring my roulet in CM, we lost 1 healer, the other refused to go solo healing, and we wait 10m for duty finder to get us another whm , i even asked my friend whm to try join via DF "join active party" and it didnt work. there is some issue with this, used to be so simple before to have a friend join when we are in need or get a random person.

CT is suffering from the same mess. It says it was finding new members but after losing 1 healer (from the very beginning), 1 tank and 2 dps and having people try to join in from outside we never got new members. From what I was getting from the people trying to get friends inside nothing was popping on for any of em. Pretty safe to say something is bugged and since most people are on new content it's been going a little unnoticed

Titan HM doing the same as well. A DPS left and we were unable to refill that slot. We still got the kill (1 stack echo), but it would have been nice to fill the slot instead of not.
