Here is evidence of the bug:
Severity: it usually results in groups disbanding.
This is a new one to me and i've seen it more than once in the past few days, what happens is that someone leaves the group or goes offline and gets kicked from a matchmade dungeon (in the above example, someone left while dead) and the matchmaker still believes your group is full despite only having 3 people. Changing leader doesn't do anything, pulling companion out and putting them away does nothing to fix it. Yes I have add-ons running but this shouldn't matter as requesting a replacement for matchmaking is a core request and we switched leaders anyways and had the same issue.
There are 2 workarounds I've discovered- if they don't fix the bug in time for the event I urge people to do either:
1. Find someone to fill from one of your guilds and complete the dungeon with them off a manual invite (this might not always be possible due to availability/class mis-match)
2. Get someone (anyone) to join the party then leave so you can re-enter matchmaking. For some reason this corrected the issue for my PUG group last night.
3.
This bug is going to become more prominent/reported as the undaunted event kicks off and will need a hotfix asap.
